Scritters
Scritters are a blue mouse-like creature that are found in all of the Wonderland Adventures Trilogy games. If you get too close to a scritter, it will move two Tiles in the opposite direction. They are harmless and can't hurt Stinkers, unless they power a mechanism. They can hold down round buttons for you. In some levels you are required to kill them or trap them in Scritter Cages. They are killed by Fireballs/Pow Magic and frozen by Brr Magic.
Trivia
Even through Scritters are harmless, they are under the category "Monsters" in the Wonderland Adventures Editor. The same applies to Dragonturtles.
