Corroded Maze is the eleventh stage of the Pikmin 3 Bingo Battle mode. This, Twisted Cavern, and Jigsaw Colosseum are the only places where one can see an Onion eject a White Pikmin seed (with the help of the +5 Rare Pikmin item).
The variation unlock order, as explained here, is A, B, C.
The players are given Red Pikmin and can later find Yellows. This layout has relatively few enemies, and little variety of those creatures.
