TechnoSqueek[1] (チューチュー Chūchū?, lit. "Chu-Chu")[2], also alternatively spelled Technosqueek,[3] is a recurring enemy in the Sonic the Hedgehog series. It is a mass-produced, mouse-based Badnik model created by Dr. Robotnik.



TechnoSqueeks are based on mice, although their general design bears a close resemblance to a blue computer mouse. They have a short tail, an orange stripe around their lower half, and a pair of black eyes on the grey areas up front that resemble buttons on a computer mouse.

Game appearances

Sonic & Knuckles

In Sonic & Knuckles, TechnoSqueeks appear in Flying Battery Zone where they quickly move back and forth on the floor, walls and ceilings without using any attacks against the player. The player can easily defeat these Badniks with a Spin Jump or Spin Attack.

Sonic Mania

TechnoSqueeks make an appearance in Sonic Mania. In line with their original debut, they appear in the Sonic Mania version of Flying Battery Zone. Their attack pattern is identical to the one they had in Sonic & Knuckles.

Powers and abilities

TechnoSqueeks have the ability to scuttle along any surface, such as walls and ceilings.
