Flomp

Rhomps are a new type of enemy appearing in the game Super Mario Galaxy 2. They appear as a green platform with spikes on their sides and have a similar face to a Pushy Wall. They move from side to side. At first glance, they seem like ordinary platforms, but after a few seconds, they make a malicious face and quickly flip over. If Mario or Luigi was on one of these platforms when they flipped, they would be knocked into the lava or into a Black Hole. They only appear in Bowser's Lava Lair.
