Spiny Skipsqueak

Spiny Skipsqueaks are a variant of Skipsqueak that first appear in Super Mario 3D World.

Super Mario 3D World / Super Mario 3D World + Bowser's Fury
In Super Mario 3D World and Super Mario 3D World + Bowser's Fury, Spiny Skipsqueaks are stationary variants of Skipsqueaks that sometimes jog in a set path. As its name indicates, it features spikes on its back, thus it can be defeated by any attack except a jump. Spiny Skipsqueaks can also make a high hop. Spiny Skipsqueaks are found usually in groups of two or more. Spiny Skipsqueaks make their first appearance in the level Really Rolling Hills.

Super Mario Maker 2
Spiny Skipsqueaks appear as placeable enemies in Super Mario Maker 2 in the Super Mario 3D World style, where they jump whenever Mario jumps. Just like Skipsqueaks themselves however, if they are pushed away from its starting point, such as by a Thwomp or Track Block, it will run back towards its starting point and even Triple Jump over obstacles to get there. If it cannot pass the obstacle, it will give up and look tired, then reset its movement pattern from its new location.
