Skipsqueak

Skipsqueaks are mouse-like enemies that appear in the Wii U game, Super Mario 3D World. Some 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. They also have cousins named Spiny Skipsqueaks.

Trivia
Their name is a portmanteau of "skip" and "pipsqueak".
