The Bot Bus is an invention of Dr. Ivo Robotnik. It was used to help him and Snively track to Freedom Fighters to a hilltop fort, (presumably Fort Acorn). He easily drove through the fort's wooden walls and confronted Bunnie Rabbot in a metal suit. He was about to crash into her when she raised her extendable legs to dodge him and Robotnik and Snively went tumbling down the hill. (StH: #26)
