'''Challenges''' are a feature of {{pb}}, unlocked at [[level]] 15. Mushrooms of various colors and sizes appear around the world, and the player can send a group of [[Pikmin family|Pikmin]] to [[Combat|attack]] them. Multiple players can join a challenge, and participants will receive [[Fruit (Pikmin Bloom)|fruit]] and a [[postcard]] as a reward, and a score that measures how well they did.

The amount of Pikmin that can be sent on a challenge by a player will increase over time based on the player's [[level]], starting at 10 Pikmin. The [[Pikmin Bloom interface#Challenge|challenge selection screen]] lets the player choose which Pikmin to send, and the strength value of the selected Pikmin can be seen in the top left corner. The higher the strength, the faster the Pikmin will be at completing the challenge.

Only three challenges can be done by a player in a day. Up to five people are able to join in on a single challenge.

==Mushrooms==

{{game help|pb|What is the distribution of different mushroom types?}}
Mushrooms are the objects destroyed in challenges. Like [[big flowers]], they grow at points of interest in the real world. They can only be seen and interacted with when they are less than 600 meters away from the player. After the challenge is complete, the mushroom is destroyed, and grows back in the same location 15 minutes later, without any input. The mushroom type that grows is randomized, but there seems to be a system where some mushrooms are removed from the selection if no players nearby have access to the corresponding Pikmin type.

Mushrooms come in various forms that differ in size and color. The hierarchy of the sizes are small, normal, large, and giant, with each size increasing in [[health]]. The larger the mushroom, the bigger the reward for destroying it. There are 8 colors of mushrooms for each size, except for giant mushrooms which only come in red. Some mushrooms have more or less health than other colors of the same size, such as gray or white mushrooms, being tied to the preferred Pikmin's attack power. The color of mushrooms can also determine the type of [[nectar]] players get as a reward.

==Process==
{{game help|pb|How does challenge multiplayer work?}}
When a mushroom is selected, either from the [[Pikmin Bloom interface#Map|map screen]] or [[Pikmin Bloom interface#Expeditions|expedition list]], the camera will focus on the mushroom, with a photograph of its corresponding real-world landmark behind it. The screen displays some basic information about challenges, as well as 5 circles that can be filled with icons of the [[Mii]]s of the players who have joined the challenge. There is a Join button which progresses to the selection screen.

In the selection screen, the player can choose which Pikmin to send. A list of all the player's Pikmin appears, and by tapping one, it can be added to or removed from the challenge group. The maximum size of the challenge group depends on the player's [[level]]. Pikmin with an advantage against that mushroom type (see the next section) may jump in the list when selected for the challenge. Selected Pikmin also appear in front of the mushroom in the camera view. There is a GO button in the lower right corner; tapping it sends all the selected Pikmin on the challenge.

Once the Pikmin are sent on the challenge, they rush towards the mushrooms and start attacking them. Most Pikmin types latch on to a mushroom and start attacking it at a constant rate, with each attack doing some damage. [[Rock Pikmin]] instead jump towards a mushroom from a distance and roll back to jump again. From time to time, Pikmin get off the mushroom, walk back to their starting position, and walk back to the mushroom to start attacking again. Each hit decreases the health of the mushrooms, though not by a set amount; see the [[#Time|Time]] section for more details. From time to time, one of the mushrooms in the group will collapse, leaving the Pikmin attacking it to start attacking another one. The intervals at which mushrooms break depend on the number of the mushrooms in the cluster: 4 for small, 7 for normal, and 10 for large, such that mushrooms break at regular intervals. For example, in a large mushroom group, one of the mushrooms will break for each tenth of health depleted.

When the health is fully depleted, the challenge is cleared. The player is provided with their score, the time the challenge took, and a star rating, followed by the Pikmin bringing a [[postcard]] about their challenge and a small number of shiny [[Fruit (Pikmin Bloom)|fruits]] to be given to the player, providing them with [[nectar]] of an uncommon type. Each Pikmin that was sent on the challenge also gains some [[friendship]] (though this actually happens at the start of the challenge, not the end).

==Attack power==
When the player is selecting Pikmin for the challenge, a power value appears in the top left corner of the screen. This shows how strong the selected squad is against that mushroom. (Note that the value displayed is rounded from the actual value.) Adding a Pikmin will increase the value by some amount. The amount depends on 5 variables: the [[Pikmin family#Types|type]] of Pikmin, its [[friendship]], its [[maturity]], whether it is a [[Decor Pikmin]], and the color of the mushroom being attacked. The equation below is the overall equation for calculating the power contributed by a single Pikmin; the paragraphs below explain what each variable means.

{{equation|PB Challenge Power Formula.png}}

Each Pikmin type has a base attack power. [[Red Pikmin]], [[Yellow Pikmin]], and [[Blue Pikmin]] all have the standard base attack power. [[White Pikmin]] and [[Winged Pikmin]] are slightly weaker, while [[Purple Pikmin]] and [[Rock Pikmin]] are slightly stronger. The exact values used are in the table below.
{|class="wikitable"
!Type
!Base attack power
|-
|Red, Yellow, and Blue Pikmin
|4
|-
|White and Winged Pikmin
|2.8
|-
|Purple and Rock Pikmin
|5.2
|}

A Pikmin's [[maturity]] contributes to how strong it is. Leaf Pikmin have the standard attack power, and each maturity level above that increases the power slightly. Rare flowers, such as pansies and roses, are stronger than regular flowers. Bare Pikmin, obtained by feeding them too much [[nectar]], are slightly weaker. The exact values used are in the table below.
{|class="wikitable"

|Leaf
|1
|-
|Bud
|1.1
|-
|Normal flower
|1.2
|-
|Rare flower
|1.3
|-
|Bare
|0.9
|}

A Pikmin's [[friendship]] contributes to how strong it is. For the purposes of the formula, the value used is the number of completed hearts. The fractions of a heart between full hearts doesn't matter, so a Pikmin with 1.1 hearts of friendship and a Pikmin with 1.8 hearts of friendship have the same attack power of 1. The number of full hearts ranges from 0 to 4, so a value in this range is used in the formula.

If a Pikmin is a [[Decor Pikmin]], 4 points will be added to its attack power. This variable in the equation can be either 0 (for non-Decor Pikmin) or 4 (for Decor Pikmin).

The final variable is the type of mushroom, and this is the last step in calculating attack power. If a Pikmin is the same color as the mushroom, its attack power will be multiplied by 2. In other cases, certain Pikmin types may have an advantage or disadvantage against certain mushroom types. The multipliers for each Pikmin-mushroom combination are in the table below.

As an example, picture a standard [[Purple Pikmin]] with 2.5 hearts of friendship and a bud on its head, against a red mushroom. This gives it a base damage of 5.2, a maturity multiplier of 1.1, a friendship value of 2, a Decor bonus of 0, and a mushroom multiplier of 1.1. Putting these values in the formula gives (5.2 × 1.1 × (1 + 2/10) + 0) × 1.1, or 7.5504. The game would round this up to 8 for displaying to the player.

==Time==
The amount of time it takes to complete a challenge (in seconds) is calculated by taking the health of the mushrooms, dividing it by the total attack power of the Pikmin on the challenge, and multiplying it by 4. For example, a normal-size mushroom with 21,000 health, attacked by a group of Pikmin with 200 attack power, should take 420 seconds or 7 minutes to destroy. Although the game presents damage as something dealt by each individual attack, each Pikmin hit actually does as much damage as it needs to decrease the health of the mushrooms at a linear rate such that the challenge finishes at the calculated time.

==Scoring==
{{game help|pb|Fully investigate how scoring works.}}
At the end of a challenge, the game gives the player a score and a star rating. Star ratings are presented as ranging from 1 to 3, but they actually range from 1 to 4. The score obtained on a challenge is entirely dependent on the attack power of the group sent on the challenge. The health of the mushroom has no effect, and there do not seem to be any hidden bonuses. (For example, attacking a small yellow mushroom with 323 attack power completes the challenge in 59 seconds, scoring 2158 points. Attacking a small white mushroom with the same 323 attack power completes the challenge in 42 seconds, but still scores 2158 points.) The exact system used to calculate scores is not fully understood.

The following table shows the approximate minimum total attack power to get a certain star rating on a certain size of challenge. The color of the mushroom does not have an effect. Values marked with * may not be exactly accurate.

{| class="wikitable"
! Mushroom size !! 2 stars !! 3 stars !! 4 stars
|-
| Small || 185 || 324 || 564
|-
| Normal || 295 || 737 || 2000
|-
| Large || 835 || 1623* || 2920*
|-
| Giant || 1134* || 2194* || 4534*
|}

It is not known how scores are calculated when multiple players join the same challenge. As completion time is easier to measure in this scenario, it's possible that it is the actual determining factor (although it varies with mushroom type). In this case, it would be reasonable to assume that the sum of all attack powers among the party needs to match the value in the table &ndash; provided that all players start at exactly the same time.

==Rewards==
{{update maintenance|Pikipedia:Pikmin Bloom update procedure}}
Once a challenge is complete, a [[postcard]] and some [[Fruit (Pikmin Bloom)|fruits]] will appear, and the Pikmin on the challenge will collect them. If too few Pikmin were sent on the challenge to carry all the rewards, only some rewards will be collected; the postcard has the highest priority. The fruit rewards depend on the star rating for the challenge.

==Strategy==
[[File:PB Attack Power Infographic.png|thumb|right|300px|An infographic explaining the calculation of attack power.]]
{{guide}}
When you first unlock challenges, you likely won't be able to get very high scores because of the limit on how many Pikmin you can send to a challenge. At this stage, focus on attacking larger mushrooms as they give more rewards for low star ratings, and send Pikmin you want to increase the friendship of, since challenges give a small amount of [[friendship]] to participating Pikmin.

After gaining a few [[level]]s and increasing your maximum challenge group size, you'll start being able to get higher scores. To optimally prepare a squad for challenges, select Pikmin that are the same color as the mushroom you'll be attacking, and Pikmin with higher friendship values (preferably [[Decor Pikmin]]). Feed them all a rare type of [[nectar]] (the types you get from completing challenges), and send them on the challenge. With a high enough level and enough Decor Pikmin, you should eventually be able to reach 4-star scores on small mushrooms.

Getting 4-star ratings on larger mushrooms requires multiple players, so if you have friends who play ''Pikmin Bloom'', consider working together to complete a challenge as quickly as possible.
