===Obscured Perplexing Pool texture===
[[File:Pikmin2 PP HiddenTexture.png|thumb|The partially-obscured texture.]]
This texture that combines two textures is used, but in each case it's either distorted or portions of the texture aren't used &ndash; the player never gets to see both parts of the texture clearly.
The bottom part of this texture, resembling a drain pipe clogged with grease, is located under the [[Shower Room]]'s entrance, but it cannot be fully seen because the cave entrance covers most of the texture. It can be seen in the Piklopedia in the same spot, but even then it's warped by the water texture above it and the Piklopedia's bloom filter; not to mention that the level model is actually [[Piklopedia (Pikmin 2)#Areas|an almost completely different model]].
The top part of this texture is seen on the chipped parts of concrete/tile in the same area, but only portions of it can be seen at a time. In the two cases where it's facing upwards, the middle section is normally covered by a metal pipe, and for the chipped concrete at the landing site, the surrounding tile part is not visible. In the other case when it's used in the crack in the Shower Room's entrance, only a quarter of it is used, and part of it's at an extremely narrow slant, making it hard to look at clearly.

There is a single unused level in ''Pikmin 2'', titled [[newtest]]. It has a Piklopedia version in another file, which is missing the section of the map with footstep sounds. It has multiple unused layouts in <code>/user/Abe/map/newtest/nonloop</code>, three of which specify enemies that are planned to spawn in certain areas, as dictated by a "readme" file found in the same directory. It seems to be a test map, based on its title and its contents, which include organized slopes, water, and clusters of enemies and objects. It overall has a basic, flat garden environment similar to the [[Perplexing Pool]].

== Unseen area geometry ==
A large amount of unseen geometry can be seen out of bounds in most areas through hacking in ''Pikmin 2''. In most cases, this indicates usage of a copy and paste feature on the modeler's modeling program, although in some cases, it implies slightly different area design at one point in development.
These include:
* A floating triangle under the buried plate in the Awakening Wood and its Piklopedia version. Its presence is likely related to the modeling process for the buried plate, since it has the texture of the plate itself.
* Petals found underground in the Awakening Wood.
* The adapters on the metal pipes in the Perplexing Pool having bottom geometry and back geometry.
* A tile block found near the landing site in the Perplexing Pool has an unusual shape underground, indicating that it might have been rotated differently earlier in development.
* A roof shingle buried in the Perplexing Pool having extra geometry that goes unseen underground.
* A wooden frame going much deeper than what is seen normally in-game.

=== Internal naming oddities ===
All content in ''Pikmin 2'' has internal names that cannot be seen in-game, like unused text. The naming of these files sometimes contains leftovers or hints to cut content early in development:
* The developer comment for the lone [[Burrowing Snagret]] in the Valley Of Repose is "{{j|ヘビガラス埋まりお宝|Hebigarasu umari otakara}}" which roughly translates to "Burrowing Snagret filled with treasure", hinting that the [[Pink Menace]] may have been once inside the Snagret.
* The names of many files used for lighting in caves indicate that a sublevel was deleted from the final cave:
** The first floor of the [[Snack Pit]] uses a lighting file called <code>Key_light_lv1.ini</code>, and there's an unused lighter version of the same file named <code>Key_light_lv0.ini</code>. The presence of this indicates a floor was cut from the Snack Pit in the final game.

This cave is known as <code>caveinfo</code> internally, and is composed of earlier versions of sublevels used in other caves, with some sublevels with unique layouts being totally cut from the game and remaining here. It has 34 floors and uses the [[Petrified Heart]], [[Regal Diamond]], and [[Tear Stone]] as placeholders for treasures in most of its sublevels.

===Pointless cave unit exits===
Caves are made out of multiple [[cave unit]]s, each with their own exit points. The game then connects these units during sublevel generation by connecting exit points. Some cave units have exit points that are useless in sublevel generation, because the resulting sublevel is always the same in-game, showing no randomization. This is because every time the sublevel is generated, it can only ever use the same cave units in the same way, so these rooms always have the same dead-end units connected to them. In addition, there is a property that controls the corridor-to-room ratio, with 0 resulting in only dead-end units spawning and no corridors, and 1 being lots of corridors connecting exit points. Where these cave units appear, this ratio is set to zero, so corridors cannot generate, resulting in the only thing to connect to them being the dead-ends. This would be functionally identical to a sublevel using a single cave unit with the dead-ends as part of the model. Shown below are the cave units where this issue arises:
<gallery>
P2CU_room_houdai2_1_metal.jpg|'''room_houdai2_1_metal''': 6 exit points.
P2CU_room_houdai_1_metal.jpg|'''room_houdai_1_metal''': 1 exit point.
P2CU_room_ike4_5_tsuchi.jpg|'''room_ike4_5_tsuchi''': 5 exit points.
P2CU_room_kingchp_tsuchi.jpg|'''room_kingchp_tsuchi''': 3 exit points.
P2CU_room_queen_c_tsuchi.jpg|'''room_queen_c_tsuchi''': 1 exit point.
P2CU_room_hitode6x6_3_toy.jpg|'''room_hitode6x6_3_toy''': 3 exit points.
P2CU_room_large_7_toy.jpg|'''room_large_7_toy''': 7 exit points.
P2CU_room_mid_tower2_8_toy.jpg|'''room_mid_tower2_8_toy''': 8 exit points.
P2CU_room_mid_tower_8_toy.jpg|'''room_mid_tower_8_toy''': 8 exit points.
</gallery>
Of special note is the last sublevel of the [[Dream Den]], which can actually show randomization in the sublevel visuals, since there are two different dead-end units that can be used for that sublevel. Normally, all of the player's attention gets diverted to defeating the [[Titan Dweevil]], carrying back the treasures, and exiting the cave, instead of the type of dead-end unit used when the sublevel was generated.
===Cave unit name oddities===
The majority of "room" styled [[cave unit]]s are named with this pattern, with a few exceptions: <code>[type]_[details]_[exits]_[style]</code>
Where "details" includes the "layout ID" of the unit, linking it with other units with the same layout in different styles, and the unit dimensions. For example: <code>room_4x4d_4_conc</code> is a room, that is 4 units wide and 4 units long, is a "d" styled layout (connecting it with <code>room_4x4d_4_renga</code> and <code>room_4x4d_4_tile</code>, which share the same layout), it has 4 exits, and it is in the concrete theme.
Some cave units have abnormal names that do not match up with the actual model or imply other details, listed below. These naming oddities are likely leftovers from earlier stages of development, where hypothetically, those names were correct in relation to the cave unit.
<gallery>
P2CU_room_manh_2_conc.jpg|<code>room_manh_2_conc</code>: Name implies there are two exit points. There is only one.
P2CU_room_spiral_1_conc.jpg|<code>room_spiral_1_conc</code>: Name implies there is only one exit point. There are five.
P2CU_room_houdai2_1_metal.jpg|<code>room_houdai2_1_metal</code>: Name implies there is only one exit point. There are six.
P2CU_room_boss_1_tsuchi.jpg|<code>room_boss_1_tsuchi</code>: Name implies there is only one exit point. There are none.
P2CU_room_hebi12x12_1_tsuchi.jpg|<code>room_hebi12x12_1_tsuchi</code>: Name implies there is only one exit point. There are none.
P2CU_room_tako2x2_8_tile.jpg|<code>room_tako2x2_8_tile</code>: Name implies there are eight exit points. There are four.
P2CU_room_queen_b_tsuchi.jpg|<code>room_queen_b_tsuchi</code>: Naming order in conjunction with <code>room_queen_c_tsuchi</code> implies the existence of <code>room_queen_a_tsuchi</code> but that unit does not exist.
P2CU_room_queen_c_tsuchi.jpg|<code>room_queen_c_tsuchi</code>: Naming order in conjunction with <code>room_queen_b_tsuchi</code> implies the existence of <code>room_queen_a_tsuchi</code> but that unit does not exist.
</gallery>
While there are "4x4" layout IDs for letters of the alphabet up until O, there is no "4x4n" or "4x4m" shape that exists. A cave unit with a "3x4n" layout ID does exist, however, but the cave unit that uses that shape is the only lettered 3x4 cave unit. There is also a "3x3m" ID that is used in the snow and concrete sets, but that ID too is the only lettered 3x3 ID.
Of special note is <code>room_boss_1_tsuchi</code> and <code>room_hebi12x12_1_tsuchi</code>; the ends of both units differ in texture from the rest of the unit, suggesting that the cave unit originally had an exit in line with their internal names, but then later had a dead end unit stitched onto the model.

* The file system in ''Pikmin 2'' has a section of files containing archives used by the game, all named after developers. Two of these folders are empty: <code>Morimura</code> and <code>Ogawa</code>, probably short for Naoya Morimura and Yuzuru Ogawa.
* An archive called <code>meck</code> is present in the folder for cave skyboxes, but all the archive contains is an empty folder called "meck".

* The game has a failsafe for where [[White Pikmin]] are unlocked but [[Purple Pikmin]] aren't, where the screen to select the amount of White Pikmin just simply shows up. This isn't seen in normal gameplay without using a [[glitch]] to skip Purple Pikmin.
* A single rogue one-sided untextured triangle is floating under the dirty plate in both the normal and [[Piklopedia]] version of the [[Awakening Wood]].
* Pikmin can die by managing to fall out of an [[area]], similarly to [[The Forest Navel]]. It isn't possible to see Pikmin die by this method in normal gameplay because there are no bottomless pits in areas in ''Pikmin 2''.
* There are waypoints for carrying objects out of the [[cave unit]] for the [[:File:P2CU room_oootakara_tile.jpg|Titan Dweevil's arena]], but Pikmin are never seen carrying objects out of the room in-game.

* The [[Man-at-Legs]] while dormant is affected by gravity. This can not normally be seen in the game.

* The [[Waterwraith]] is set to hold the [[Professional Noisemaker]] on all sublevels of the [[Submerged Castle]]. It is completely impossible to bring non-Blue Pikmin into the Submerged Castle, as the game is coded to not count non-Blue Pikmin when bringing Pikmin into the Submerged Castle, so this property is pointless in normal gameplay.

* Gas pipes have a feature to turn on and off on a loop. They are set to be spewing for 3 seconds, but because they are set to be off for 0 seconds, the entire on-and-off feature has no purpose. This is also not the result of copying the data from the fire geyser, since that object uses different durations (2.5 seconds for being on).

* [[Unmarked Spectralids]] have 200 health points but die on one hit. Likewise, [[Honeywisps]] have 99999 health points but also die in one hit.

* In ''Pikmin'', there is an unused feature that makes Pikmin get [[throw]]n higher the longer the Pikmin is held. This feature has no effect on gameplay since the normal height values and the "fully charged" height values are the same. In ''Pikmin 2'', these values still exist, and are still the same for the normal and full charge amount, but the code for the feature itself has been removed.

* Enemies in ''Pikmin 2'' have set ID numbers, and are spawned using the ID number that is assigned to the enemy. Four of these numbers, <code>39</code>, <code>64</code>, <code>82</code>, and <code>100</code> are never used; they crash the game when spawned. This is because the files for <code>39</code> and <code>64</code> were deleted, and ID numbers <code>82</code> (internally, <code>Pom</code>) and <code>100</code> (internally, <code>UmiMushiBase</code>) appear to be template files for variants of [[Candypop Bud]]s and enemies in the [[mollusking family]], respectively.

** Interestingly, <code>82</code> appears after all of the ID numbers for the specific Candypop Buds, which are numbers <code>3</code> through <code>8</code>. The ID number for the [[Ranging Bloyster]] appears much later in the list as <code>71</code> (internally, <code>UmiMushi</code>) while the ID for [[Toady Bloyster]] is <code>101</code> (internally, <code>UmiMushiBlind</code>), so it's possible that some of the ID numbers shifted around during development. Additionally, the enemy that has the ID of <code>39</code> is set to spawn in a unused layout file for [[newtest]] and is referred to as "{{j|フエフキムシ|Fuefukimushi|Flute Player Bug}}" in comments, which is similar to the [[Antenna Beetle]]'s internal name. This enemy would be able to spawn in the [[Awakening Wood]] as dictated by a <code>readme.txt</code> file found in the same directory.
