Flomp

Kurunba (also known as Flimps) are types of enemies 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 Tsukidashi-kun. 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 high into the air. They appear in only two galaxies, Bowser's Lava Lair and the Grandmaster Galaxy.
