In Sonic Chaos, Boing-o-Bots are very similar to Moto Bugs, except for a few design differences. They have a Spring on top of them and wheels on the side of their bodies, as opposed to the Moto Bugs' single wheel on their bellies. Also, their pincers are yellow instead of white and blue and they lack engines on their rears.
Like in Sonic Chaos, these enemies roam back and forth with Springs on their shells that will bounce the player upward. In order to destroy them, the player must roll into them from the sides with a Spin Attack. Several of these Badniks also appear during the fight with the Tart Turtle to help the player reach said boss in Great Turquoise Zone Act 3.
Like other enemies in the game, they do not have any Animals inside them that they release upon their destruction.
Boing-o-Bot's Japanese name, "Bane Motora", comes from "bane" (ばね,"bane"?) meaning "spring", and Motora, the Japanese name of the Moto Bug.
