The Technosqueek[1] (チューチュー[2] Chūchū?, lit. "Chu-Chu"), alternatively spelled TechnoSqueek,[3] is an enemy that appears 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.



In Sonic & Knuckles, and the lock-on game Sonic the Hedgehog 3 & 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. Doing so will release the Animals inside of them and award the player with 100 points.

Powers and abilities

Technosqueeks can stick to virtually any surface and travel on it with ease.


  • Technosqueeks, along with Blasters, are pictured and listed in the western manuals of Sonic the Hedgehog 3, even though they do not appear in the game.[3] The Technosqueeks, along with other enemy sprites from Flying Battery Zone can also be found in Sonic the Hedgehog 3's game data.
  • The Technosqueek's Japanese name "Chu-chu" is Japanese for "squeak".
