Cloud

From RayWiki

Clouds are platforms found in all worlds of Rayman, except Dream Forest. There are many kinds of clouds, some of them being static, the others following various trajectories. Among static clouds, there are rebounding and trampoline clouds, the latter allowing Rayman to jump higher with a certain timing, but also pierced clouds, which disappear after Rayman jumps onto them, or at regular intervals. During the battle against Mr Stone, moving pierced clouds appear, but nowhere else.
