Chomper
Chompers are one of the common enemies that appear in every Wonderland game.
Classic Trilogy
In the Classic Trilogy, Chompers will attempt to reach a certain character, but are not intelligent enough to go around walls. They come in two versions, Red Chompers and Gold Chompers. Red Chompers follow Stinky or Qookie if he/she's present, and Gold Chompers follow Loof or Peegue if he/she's present. An interesting fact is Chompers tend to follow Stinky and Loof more than Qookie and Peegue.
Wonderland Adventures
In the Wonderland Adventures series, they come with a fully customizable speed setting and a special setting, and will go around walls to reach the player character. The special setting can be set to --- (Chomper acts normally), Ghost (Chomper is semitransparent and goes through certain collectible objects), or Glow (Chomper glows in the dark). If the speed is set to a low negative number (e.g. -23), the Chomper will cease to move.
