Bushbubble is a Badnik from the Knuckles' Chaotix, found in the Botanic Base area. It is described as "an air-headed bubble-brained Badnik (that) can do a lot of damage". The robot is armed with revolving spikes that look like leaves to blend in with the environment.
Although Bushbubble has never appeared in a strip of Sonic the Comic, it was one of the Badniks featured in the Badnik Alert! section of the Knuckles Knock-Out Special. Despite it's ever-turning weapons, Bushbubble received a Danger Rating of 1, making it the weakest Badnik in the collection.
