Checkerboard Cave
Item location in Light World near Desert Palace, requires mirror to access. Contains one chest. Named for the checkerboard patterned push blocks inside.
In very rare Randomizer cases and particularly devious Plandos, Checkerboard Cave can actually contain the Moon Pearl even though it can only be accessed by using the Mirror from Misery Mire, which would require the player to traverse the mire in Bunny mode.
