Challenge Mode (Pikmin 2)
Challenge Mode in Pikmin 2 is very different from the one in the first game. To unlock Challenge Mode, you need to collect The Key from the final floor of the Citadel of Spiders in the Perplexing Pool. Challenge Mode takes place in many cave areas and you'll need to collect The Key in each to advance through sublevels, and so complete the level; doing so unlocks further levels. There are 30 levels in all.
In each sublevel, a time limit is given, within which you must advance to the next sublevel or fail the challenge. Being awarded a White Flower upon completion means that one or more Pikmin has died, while a no-death completion earns a Pink Flower. A widely held misconception is that in order to beat challenge mode, one must collect all the treasures and have no pikmin losses - but only the key on each level is required.
