Pikmin Forever/Challenge Mode

Pikmin Forever ' s Challenge Mode is a non-canonical game mode devoted to challenging the player to a variety of Pikmin tasks. It is unlocked by collecting the Peculiar Gemstone in the main game, and can be accessed from the main menu. It contains 100 challenges of various rules, and each challenge offers four prizes in the form of objects, tools, and settings to be used in Sandbox mode. In addition, 50 of the challenges contain gems/semiprecious stones themselves, each of which unlocks a music track for Sandbox mode stages and 5 Pikgems to be used in a difficult challenge.

The challenges are presented in a branching order, where completing one challenge might unlock several new challenges which will lead to still other challenges. Eventually this order culminates in one of the three Championship challenges, which disallow Pikgems and cannot be accessed until a number of challenges have been completed.

Challenge Mode also introduces Challenge Pikmin, who are present in some challenges and only last if their thirst for green nectar is constantly quenched.

Rules
There are two types of Challenge: Regular and Twist. Regular challenges have one of 8 different goals, while Twist challenges have one of 12 different twists on regular gameplay. There are 64 regular challenges and 36 twist challenges. Each goal (except Championship) comes with two sets of applicable "Extras," which are extra caveats that increase the difficulty of the challenge. Achieving the goal alone will earn one prize, completing the challenge with either of the Extras activated will earn a prize each, and completing the challenges with both Extras activated at once will earn a final prize.

For all challenges, a Pikmin extinction or one leader down automatically ends the challenge.
