Contrast Cave is a cave that came by when Drawcia turned Dream Land into a world of paint. As the name specifies, it is a cave of contrast. One part contains Thudds and pits, another consists almost entirely of water, and the last part is home to tons of blocks and a small no-paint zone.
A room guarder is in this level. Several Blippers and falling rocks try to crush and damage Kirby. The Stone ability is very helpful here, as it makes Kirby impervious to the stones and the Blippers' attempts to swim into him; all the while damaging them seriously.
