Spiny Skipsqueak

Spiny Skipsqueaks are sub-species of Skipsqueak 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 except a jump-related one because of the spike on their head. However, Spiny Skipsqueaks have a good jump height which makes them dangerous enemies. The mice are usually found in groups of two or more. Spiny Skipsqueaks make their first appearance in the level Really Rolling Hills. They also have cousins named Skipsqueaks.

Trivia

 * They slightly resemble Porcupos from Super Mario Bros. 2.
