Technosqueek

Technosqueek (チューチュー, Chu-chu in Japan) is a mouse-like badnik that appears in the Flying Battery Zone in Sonic & Knuckles. Its design is a combination of a rodent mouse and a computer mouse. Technosqueek has the ability to run back and forth along the ground, the walls, and even the ceiling.

Trivia

 * An unnamed mouse that appears in the Gene Gadget stage in Sonic 3D is similar to Technosqueek.
 * Technosqueek is pictured and named with all the badniks in the American Sonic the Hedgehog 3 manual even though he does not appear in that game.
