Venus Guytrap

A Venus Guytrap is a plant in Wario Land: Shake It! which closes around Wario after a set time. Yellow-and-red Guytraps take longer than red-and-pink ones to close. Wario needs to shake to get out. If Wario jumps on a Guytrap and then immediately jumps again, he can be on top of it, allowing him to reach high places.

Trivia

 * Their name is obviously based off a Venus Flytrap, just like the Venus Firetrap.
