Cave: Difference between revisions

'''Caves''' ({{j|洞窟|Dōkutsu|Cave}}) are the underground areas in ''[[Pikmin 2]]'', of which 14 exist in all. Although there are several overground [[area]]s, most [[treasure]]s are found in caves, so most of the time playing the game is spent down them. They are also featured in ''[[Pikmin 4]]'', but aren't [[Randomization|randomly generated]] like in ''Pikmin 2''.

In ''Pikmin 2'', the time of [[day]] does not pass while the player is in a cave, and their floors are generated [[Randomness|random]]ly each time, but follow a specific layout scheme. According to earlier versions of the game, this is because the space-time continuum was warped due to the cave's geomagnetic radiation field.{{cite web|quote=A geomagnetic radiation field underground must have warped the space-time continuum. / Even my record of the terrain has been erased.|http://tcrf.net/Proto:Pikmin_2/Cutscene_Text#Return_to_the_Surface|Proto:Pikmin 2/Cutscene Text|The Cutting Room Floor}} The final version's instruction manual simplifies this and simply calls it "a powerful magnetic field".{{cite quote|Because of a powerful magnetic field deep under the surface, time does not pass underground.|Explanation|page 25 of the manual}}{{cite quote|The powerful magnetic field between the surface and underground can have peculiar, unexpected results. You can't rely merely on your memory, as familiar areas can often appear foreign.|Explanation|page 26 of the manual}}

Caves are entered though [[#Hole|holes]]. To enter one, the player must press {{button|gc|a|wii|a}} while near it. If the other leader is alive, it'll instantly join the party, regardless of distance. Any [[Pikmin family|Pikmin]] under the current leader's control will jump down with them, and any that are [[idle]], working, or on an idle leader's group will return safely to their [[Onion]]s. Once the player enters a cave, there is no way to increase Pikmin population save for [[Bulbmin]] and/or [[Queen Candypop Bud]]s. It is not possible to enter a cave without Pikmin.

Most objects respawn between visits to the same cave, including enemies. Treasures will not reappear once collected, and some Candypop Buds that have a [[Candypop family#Maximum Pikmin requirement|maximum Pikmin requirement]] will also not show up.

==Sublevels==

Each cave is divided into several sublevels. Each sublevel consists of a small area, that gets [[#Generation|randomly generated]] every time it is entered, and will usually have at least one treasure and a few enemies. The shortest cave – [[Emergence Cave]] – has two sublevels and the longest – [[Hole of Heroes]] – has fifteen.

When a cave is entered, the player will land in its first sublevel, and will be able to proceed through that cave's sublevels in order through the use of [[#Hole|holes]]. When, {{button|gc|a|wii|a}} is pressed near a hole, all Pikmin and live leaders will jump down the hole, landing in the next sublevel. Planted Pikmin will remain in the same sublevel and be lost forever. Some sublevels have [[geysers]] that allow the player to safely leave a cave from that sublevel.

Every time a sublevel is entered, the game is [[Saved game|saved]], so if the player turns the game off and then back on again, they will start in the same sublevel, but it will be generated randomly again.

Sublevels can be roughly categorized into three types:

'''Normal levels''' usually have a few harmful enemies, and sometimes don't have any treasure.

'''[[Rest sublevel|Rest levels]]''' either lack enemies or only have harmless enemies (exceptions being [[Doodlebug]]s and [[Bulbmin]]). Rest levels have Pikmin-supporting items, such as [[nectar]], [[ultra-bitter spray]], [[ultra-spicy spray]], or [[Candypop Bud]]s. These levels usually lack treasures, and feature [[Music in Pikmin 2#Rest|special ambient music]]. Most rest levels also have a [[geyser]] available, so the player can return to the surface if they have a low number of Pikmin.

'''Boss levels''' contain one or more large [[boss]]es, are usually the final level of a cave. The only cave without a boss level is the [[Emergence Cave]], and the one with the most is the [[Hole of Heroes]]. When the boss is defeated, it often drops an [[upgrade]] for the [[leader]]s' space suits or ship.

===Final floor===

The deepest sublevel of every cave is known as the '''final floor''', or the '''final level''' in the European [[region]] of the [[New Play Control! Pikmin 2|''New Play Control!'' version]]. In all caves except for the [[Emergence Cave]], the final floor is a boss level, as described above. Since there are no deeper sublevels, all final floors contain a [[geyser]] for the player to return to the surface and end their cave mission. These geysers are usually placed to be easily accessible before the boss arena, making most boss battles easily skippable, at the cost of missing the boss's [[upgrade]]. The boss will remain present until it is defeated; the player can always return at a later time.

As the player drops into the final level, the game announces this by playing a distinct jingle, along with displaying the words "FINAL FLOOR!" or "FINAL LEVEL!" in large, yellow letters, before the player regains control. Additionally, on the [[HUD]], the word "SUBLEVEL" in the top-right corner is replaced with the words "FINAL FLOOR" or "FINAL LEVEL" in yellow, depending on the region and console.

[[File:Cave.png|thumb|The hole used to go down to the next sublevel. These look the same as entrances to caves above ground.]]

To enter a cave, the [[leader]]s and Pikmin must dive into a hole. To go from one sublevel to the next, they must also go down a similar hole.

The holes are round, rocky mounds, with a small hole in them. On the cave entrance hole, if the cave has uncollected treasure, wisps of steam will come out, and the screen will become foggy when the hole is approached. Inside a cave, the hole to a next sublevel will always contain steam, but will not fog the screen.

===Exits===

In {{p4}}, some caves have separate holes that are exited through once the player reaches the bottom and returns to the surface. These usually allow them to access areas they otherwise couldn't as well as provide a secondary entrance into the cave.

Even though most sublevels are [[Randomness|randomly generated]], there are consistent themes shared between them. The following is a list of themes used in the game, based on what the [[#Generation|units]] are called in the game's files. The screenshots are from [[Challenge Mode (Pikmin 2)|Challenge Mode]] stages, not story mode caves.

;Concrete

: [[File:Concrete Maze.jpg|thumb|left|120px|[[Concrete Maze]].]] This design features plants, sandy floors, and concrete walls, with concrete floors sometimes as well, alongside blue rusty pipes at times. This design resembles a basement house foundation and is most likely meant to be one. [[Egg]]s and [[Bomb rock|bomb-rocks]] will occasionally fall from the cave ceiling.

: [[File:Brawny Abyss.png|thumb|left|120px|[[Brawny Abyss]].]] This design has metal floors and low walls, making it possible to [[throw]] Pikmin, and ward some enemies, [[Pit|out of bounds]]. It frequently contains [[Careening Dirigibug]]s, [[Gatling Groink]]s, or [[Lithopod]]s, with bomb-rocks appearing on occasion. The first area with a floor like this is the first sublevel of the [[White Flower Garden]].

{{clear}}

: [[File:Cave of Pain.jpg|left|thumb|120px|[[Cave of Pain]].]] A common sublevel design in the [[Valley of Repose]], these sublevels have floors blanketed with snow, and have stone – and occasionally brick – walls. The floors are commonly littered with dying [[Figwort]]s. [[Hairy Bulborb]]s and [[Snow Bulborb]]s are often present here.

: [[File:Emperor's Realm.jpg|thumb|left|120px|[[Emperor's Realm]].]] This theme represents a very basic type of cave, with soil floors and stone walls.

: [[File:Lost Toy Box.png|left|thumb|120px|[[Lost Toy Box]].]] These sublevel designs are in caves such as [[Glutton's Kitchen]] and the [[Dream Den]]. These levels are often filled with giant toys and treasures that are used for food, entertainment, and office supplies. The borders of the sublevels are smaller toys that Pikmin and [[Enemy|enemies]] can cross, but not [[leader]]s, similar to the garden theme. They sometimes can be covered with a large carpet or wood flooring that stretches for the entirety of the floor.

{{clear}}

: [[File:The Giant's Bath.jpg|thumb|left|120px|[[The Giant's Bath]].]] Bath tiles cover nearly the whole sub-level, and many [[hazard]]s are found on these types of design, mostly [[water]]. [[Wogpole]]s will sometimes fall from the cave ceiling.

Some caves have a background (also called a "skybox", or "VRBOX", as they're known internally), as a wall and/or bottom way off in the distance. Because they're so far away, it may be hard to see them over the fog and lighting. Designs that are meant to give off the idea that the leaders and Pikmin are enclosed in a burrow do not have a background, but other sublevels normally do. There can be any sort of sublevel theme and background combination.

When a sublevel is entered, the game generates it [[random]]ly; it starts by building random terrain, and then populates it with random objects.

A sublevel's terrain is composed of several [[cave units]] stitched together. Each unit can be a dead end, a corridor, or a room, and has some spots where objects can spawn; each spot contains data about the amount and type of object that can spawn there. In each sublevel's configuration, there is data about which cave units it is allowed to use, and data about how the dead ends, corridors, and rooms should work in terms of quantities. The game then uses this information to randomly create and connect cave units.

Each sublevel's configuration also has information about what objects to spawn. Entries listed in this information specify what type they are, what object to spawn, a minimum amount, a random filler weight, spawn location, and some other properties. Depending on these properties, different entries are processed differently by the game. With this in mind, entries can be thought of as belonging to one of five different "categories". As a general rule, the "main" category contains enemies, the "decorative" category contains plants, the "treasure" category contains loose treasures, the "gate" category contains gates, and the "dead end" category contains objects specifically meant to appear in dead ends.

On the wiki, each sublevel section in a cave's article contains a basic list of objects that can spawn, as well as their amounts. It also contains a more detailed list that explains what objects the game wants to spawn, in what order, and under what details. These lists reflect the sublevel's data in the game files. Though the basic list can be changed to better document what really happens in-game, the detailed list always reflects what the sublevel's data says. In the detailed list, the ID of each entry is not something recognized by the game, but exists to make the list easier to understand.

After generating the sublevel's layout, the game follows a complex process to spawn objects in it. The following is an outline of this process:{{cite web|https://pikmintkb.com/wiki/Cave_spawning|Cave spawning|Pikmin Technical Knowledge Base|retrieved={{date|27|January|2021}}}}

#* This process is split into four sub-categories, which reflect the entry's spawn type.

#* For each sub-category, respect the minimum amounts first. Then, without going beyond the "main" category object limit defined in the sublevel, add some random filler amounts, if there is any entry with random filler weight.

#* For each sub-category, spawn the minimum amounts first. Then spawn filler objects (if any) picked at random.

#* Caves in [[Story Mode]] don't make use of this since every treasure is fixed.

# Spawn the minimum amount of objects of the "dead end" category.

#* Cannot go beyond the "gate" category object limit defined in the sublevel.

Because the sublevel generation doesn't use many fixed numbers, and instead opts to use statistics and randomness to generate diverse sublevels, the game can create a sublevel where some objects in its generation data do not spawn. Sometimes an object has a minimum amount of 0, and as luck would have it, it was never chosen when filling out objects at random. At times however, a sublevel may physically be unable to accommodate some of the intended cave units or objects. For example: [[Frontier Cavern]] sublevel 4 wants to spawn a Violet Candypop Bud (in a dead end). In one attempt, the generated sublevel has 4 dead ends, so both treasures, the hole, and the Violet Candypop Bud appear in dead ends. But in a different attempt, the game generates a sublevel with 3 dead ends – only the treasures and hole will have a spot, and the Violet Candypop Bud will not show up. This happens often with decorative objects, but can, in rare cases, [[Mistake#Missing sublevel objects|happen with important objects]]. Players should be wary about this possibility, and if they find an important item is missing, they can reset the console and try for another sublevel layout.

* There aren't enough cave units of a given type to fit all objects that want to go in these units.

* There aren't enough spawn points of a given type in the entire sublevel to fit all objects that want to use them.

* The object spawns [[out of bounds]] (spawn points randomly offset the spawned objects by an amount).

Note that when the sublevel has finished generating, the game may purposely delete some objects for gameplay reasons. This happens to treasures in Story Mode that have already been collected, and Candypop Buds that do not meet the [[Candypop family#Maximum Pikmin requirement|maximum Pikmin requirement]].

Note also that the algorithm has no logic to figure out if the player can logistically reach and recover a treasure in the cave layout it generates. This is usually no problem, but in Hole of Heroes sublevel 6, it can result in one of the treasures being unobtainable, as explained [[Hole of Heroes#Sublevel 6|here]].

When entering the first sublevel of a cave, the game may or may not switch the player's active leader. This does not happen when the player goes from one sublevel to the next, making it mysterious as to why the leader changes seemingly randomly when going to the first sublevel.

In reality, this happens because of a simple glitch. In order to decide what leader to turn active whenever a sublevel is entered (be it the first or not), the game reads a variable in memory. This variable is also saved onto the [[Saved game|save game data]] and loaded from it. It is set whenever the player goes from one sublevel to the next, which explains why, when the next sublevel is loaded, the game selects the correct leader. However, this variable never gets set when the cave itself is entered. This means that when the first sublevel is finished loading, the game reads the variable, and uses an outdated value, last updated when a sublevel hole was entered. This glitch was not fixed for the ''New Play Control!'' rerelease.

It can also be noted that [[Challenge Mode (Pikmin 2)|Challenge Mode]] uses a different behavior, without a glitch, and that the default value of the variable is 0, meaning that at the start of the game, before the player goes from one sublevel to the next, the game will make Olimar the active leader when entering a cave.

When entering a cave or sublevel hole, each leader grunts as he jumps. However, the first leader to jump will always make Olimar's sound effect, and the one behind will always make Louie's, regardless of the existing leaders and their order. The only exception is if the second leader is fallen, at which point only the first leader will grunt, still with Olimar's voice.

===Technical discrepancies===

Even though the cave and sublevel information is present in human-readable format within the game's files, some of their settings appear to make no sense, as the values in the files don't match up to what happens in-game. The following assumed discrepancies have been noted:

*Property {f013} (隠し床, meaning "Hidden floor") of a sublevel indicates whether there's ground under the [[cave units]] or if it should be simulated. This is due to the fact that toybox and garden levels' units do not contain ground. However, sublevel 3 of [[Snagret Hole]] has this value set to 1 as well, despite the fact that soil-type units always have a ground.

*Sublevel 8 of the [[Dream Den]], sublevels 1 and 2 of the [[Hot House]] and sublevels 1, 2, 4, 5, 6 and 7 of the [[Collector's Room]] all have their property {f00A} (VRBOX, the "skybox" model) set to "vrbox". Both sublevels of the [[Green Hole]] have that property set to "f010". Both of these values are invalid, and the game defaults to having no "skybox".

*The final sublevels of the [[Subterranean Complex]], the [[Hole of Beasts]] and the [[Bulblax Kingdom]] all have property {f010} (階段を壊す岩で隠す(0=オフ 1=オン)) set to 1. This property decides whether the hole to the next sublevel should be [[clog]]ged or not. The oddity here is that the final sublevel does not have a hole.

*The final sublevels in the [[Cave of Pain]], [[Red Chasm]], [[Collector's Room]] and the [[Breeding Ground]] all have property {f007} (帰還噴水(1=あり)) set to 0. This property decides whether a level contains an escape [[geyser]] or not. Naturally, all final sublevels contain one in-game, so the fact that these sublevels have that property set to 0 is a mystery.

==Glitches==

{{game help|p2|Confirm the glitch where the Pikmin don't jump down and remain idle. If confirmed, add it to the glitches page.}}

*[[Glitches in Pikmin 2#Cave hole glitch|Cave hole glitch]]: It is possible for a leader to end up inside the cave hole's geometry, if he's placed on the hole's spawning point before it spawns.

*[[Glitches in Pikmin 2#Cave death count glitch|Cave death count glitch]]: If a Pikmin is suffering from a hazard and the player chooses to go to the next sublevel, the Pikmin will still have the suffering animation when jumping down the hole. If they made that last cry, they will nevertheless be alive on the next sublevel, but the total Pikmin lost count will increase.

*[[Glitches in Pikmin 2#Fake Pikmin extinction|Fake Pikmin extinction]]: By entering a cave and [[dismiss]]ing at the same time, the game will let the player enter the cave with no Pikmin. It then instantly announces a Pikmin extinction.

*There is a glitch that can happen when proceeding to the next sublevel. In the animation where everybody jumps into the hole, some Pikmin may appear [[idle]] and won't jump in. Thankfully, these Pikmin that don't jump in will appear on the next sublevel.

==Caves in ''Pikmin 4''==

Caves are shown to return in ''Pikmin 4''. But they aren't [[Randomization|randomly generated]] like in {{p2}}. Caves are accessed via black tubes with blue lids on the surface. On footage from the Japanese website, one can be seen with a red flag attached to it, presumably meaning that it's been completed, similar to ''Pikmin 2''. Some [[cave units]] originally from ''Pikmin 2'' such as <code>room_hitode4x4_3_metal</code> and <code>room_dan4x4i_3_conc</code> are known to return with an updated design. Currently, six caves are known: "[[Burrow of Beginnings]]", the first cave entered, "[[Last-Frost Cavern]]", where Ice Pikmin are discovered, "[[Industrial Maze]]", "[[Crackling Cauldron]]", “[[Aquiferous Summit]]” and “[[Hectic Hollows]]”.

These caves have large puzzle-oriented floors. They can be seen with a myriad of hazards, including fans, rails, [[Bouncy Mushroom]]s, [[conveyor belt]]s, floating platforms, and more.

Four distinct types of cave floors can be seen in the February and June trailers: one that looks like a standard dirt cave, another that's themed around metal and seems to take place inside of a shed, one with a muddy floor and brick walls, one taking place over metal platforms in a dark void, one taking place in an enclosed area with blue tiles on the walls and floor, and one that appears to take place inside what is presumably either a display terrarium in an aquarium/a pet store or a science museum's water table. Notable content that can be seen includes:

** Dirt walls.

** Tiny fungi.

** Dead leaves scattered about.

* Shed:

** Metal rings and dirt on the floor.

** An LED {{w|dot matrix}} display, showing a number. All trailer footage just shows the number "01".

** In the cave's background, what is either the sunlight shining from the slits on the door of the shed, or some {{w|fluorescent lamps}} that are on.

** Support beams in the background, possibly made of wood.

* Brick cave:

** A wall with an ocean painted on it.

** Glass walls.

** Fake logs with what appears to be {{w|astroturf}} on top of them.

** In the background, cylindrical aquariums built into pillars can be seen, along with blurry visages of soda fountains behind them. What appears to be a blurry exit sign and a vending machine can also be briefly seen.

==Trivia==

*Leaving a cave will always make the game switch to Captain Olimar, regardless of whatever leader the player had active before leaving.

*In an earlier version of ''Pikmin 2'', the player could leave caves with half of the collected treasure if they leave through the [[pause menu]]. However, all Pikmin would be lost in doing so.{{cite web|quote=Escape without your Pikmin? (Retain 1/2 of treasure found.)|https://tcrf.net/Pikmin_2/Early_English_Script#Pause_Menu|Pikmin 2/Early English Script|The Cutting Room Floor}}

*The [[Music in Pikmin 2#Enter cave|fanfare]] that plays when jumping into the first sublevel of a cave is played again on organ during the [[Music in Pikmin 2#Enter new sublevel|fanfare]] that plays when a deeper sublevel is entered.

*On the [[Subterranean Complex]]'s third sublevel, and possibly similar levels too, it is possible for the sublevel's hole to spawn on the zigzagging path instead of dead end or somewhere in the open. Since this place is so tight, it spawns a bit on the edge, and makes it possible for leaders or Pikmin to climb up the hole's mound and fall off the stage.{{cite youtube|cDQP8AxcwsE|of a hole close to the edge|m=56|s=42}}

*All story mode caves in ''Pikmin 2'', besides the caves in the [[Wistful Wild]], have some hint of some part of their contents as background scenery nearby. Examples of this would be the concrete block near the [[Citadel of Spiders]] (hinting towards the concrete theme), the ceramic tiling near the [[Frontier Cavern]] (hinting towards the brick wall designs) and the [[Shower Room]] being enclosed in a tiled tub (hinting towards the tile theme used in said cave).

*In "dirt"-styled sublevels, it is possible to see [[dig|buried]] treasure through the floor, in some angles.{{cite web|https://www.reddit.com/r/Pikmin/comments/nitcv2/tfw_you_realize_you_can_see_buried_treasure/|Post|reddit|published={{date|22|May|2021}}|retrieved={{date|3|May|2022}}}}
