Trapdragon

Trapdragons are enemies that appear only in Super Mario Galaxy 2. Their name is a portmanteau of "trap" and "." They appear only in the Honeybloom Galaxy and Honeyhop Galaxy. Trapdragons resemble pink flowers and can be used as platforms, but if Mario or Luigi steps on one of these, it soon closes up, devouring the object on it. If Mario or Luigi is swallowed, he loses a wedge of health. Trapdragons are usually airborne or floating over shallow ponds. After snapping shut for a few seconds, a Trapdragon reopens and can be used again. One can avoid lasting damage from Trapdragons, though. If a coin is floating above a Trapdragon, one can get trapped by the flower and spat into the coin, having full health but still flashing red from damage. Since no power-ups can defeat them, Trapdragons are invincible.

The mouth animation of Trapdragons is similar to that of Piranha Plants in Mario Kart 64.
