Tsuno-tsuno (ツノツノ[1]?) is an enemy that appears in Sonic Chaos. It is a mass-produced Badnik model created by Dr. Robotnik.



Tsuno-tsunos are rather bizarre, rutabaga-looking Badnik with a pointy yellow forehead, a round orange body and a pair of black eyes. They also have blue pincers with gray claws and a pair of wheels to move around with.


Tsuno-tsunos are only encountered in the higher sections of the Sleeping Egg Zone. They do not have proactive offenses as they simply drive inexorably forward and jump occasionally so the player will take damage by colliding with them. When landing above Monitors, they do multiple rapid jumps.

These Badniks are easily dispatched by a Spin Jump or Spin Attack. Like other robots in 8-bit Sonic games, no Animals pop out of Tsuno-tsunos when they are destroyed.


  • The Tsuno-tsunos' name comes from Japanese sources, as the term Veg-o-Bots[2] or Bounding Badniks[3] may refer to Tsuno-tsunos or Froggers; despite their appearance, they are nearly identical in function.
  • Tsuno-tsuno's name comes from "tsuno", which is Japanese for "horn".
