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. Chompers make "Nyap, Nyap" sound when they move.
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.
