Hot Lips

Hot Lips is a lava dinosaur that lives in lava in Super Mario World 2: Yoshi's Island, Yoshi's Island: Super Mario Advance 3 and Yoshi's Island DS. This dinosaur spits a stream of lava out of its mouth to attack the Yoshi and Baby Mario (in a manner similar to that of the Spray Fish). If the Yoshi is hit with lava, he will be knocked out instantly. Hot Lips looks a lot like a Blargg; however, Hot Lips has pouter lips and larger eyes. They are invincible to all but a POW Block, and Eggs stun it for a few seconds.

Hot Lips reappears in Yoshi's New Island, but it's lava stream no longer causes instant death, instead it merley causes Yoshi to drop Baby Mario like most other enemy attacks.
