Here's a classic baddie from an old show and PS2/GameCube game.

The first stage is the Newborn, then the Hopper (it is what I call it), then the Stomper, then the big Gromp, then lastly it final evolution, the Mongro. For whatever you do...do not sing good or they'll attack you. If you sing bad...well, as insulting as it is, you're safe, and bad singing will make them sleepy.
