Scritters are blue rodent like creatures that are found in the Wonderland Adventures game series. If you get too close to them, they will get away from the opposite directions. They are harmless and can't hurt any Stinkers. They can hold on round buttons for you, in some levels you need to trap the Scritters in cages. They can be killed by fireballs, Pow magic and get frozen by Brr magic.
Even though, Scritters are harmless, but for some reason they are under the "Monsters" category in the Wonderland Adventures Editor. This is the same thing for the Dragonturtles, which are also harmless.
