Skipsqueak

Skipsqueaks are mouse-like enemies that appear in Super Mario 3D World. Their name is a portmanteau of "skip" and "pipsqueak".

Super Mario 3D World
Some Skipsqueaks are stationary and some jog around in a set path, and can be defeated by any attack. However, Skipsqueaks have a good jump height which makes them dangerous enemies. The mice are usually found in groups of two or more. Skipsqueaks make their first appearance in the level Really Rolling Hills and make appearances in Grumblump Inferno and Rainbow Run. There is a subspecies of this creature known as Spiny Skipsqueaks which also appear in Cookie Cogworks and again in Rainbow Run.

Super Mario Maker 2
Skipsqueaks and Spiny Skipsqueaks reappear as enemies that can be placed in Super Mario Maker 2 stages. Skipsqueaks jump whenever Mario jumps, and are not affected by Conveyors.
