You may be looking for Anton Brooke.

Anton (アントン in Japan) is ant-type badnik created by Doctor Robotnik which only appears at Palmtree Panic in Sonic CD.

DescriptionEdit

It is based on terrestrial ants and seems to be an upgrade of the Moto Bug from original Sonic the Hedgehog, which lacks any weaponry while the Moto Bug was armed with razor arms.

But like Moto Bug, Anton simply rolls back and forth along the ground, never going down platforms. It is easily avoided and destroyed. When broken down due to age, these badniks move considerably slower, and have a depressed look on their faces. Like other badniks in the game, Anton is powered with Little Planet's flower.
