Flomp

Flomps (known as Floating Plates in Super Mario Galaxy 2 Prima guide) are a type of Thwomp 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 Bomp. 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 is on one of these platforms when they flip, he will be knocked high into the air. They appear in only two galaxies: Bowser's Lava Lair and the Grandmaster Galaxy.

Flomps make a reappearance in Mario Party: Island Tour, for the Nintendo 3DS, acting and looking like they did in Super Mario Galaxy 2. They appear in the minigame Flip Out.

Trivia

 * Flomps' method of attacking is very similar to that of some specific platforms in World 5-4 from Super Mario Bros. 3.
