Slurp Guys are a variant of Shy Guys that appear in Paper Mario: Color Splash. They carry straws in their mouths, which they can use to steal the colors of other things. There are blue, red and yellow Slurp Guys. When they attack in a battle, they drain one of Mario's three color bars according to their color, so he cannot paint cards of that color until he recovers his paint.

If Mario runs out of health during a battle, they come and Mario gets a Game Over!
