The bubble motorcycle is a vehicle that only appears in the episode "Burst Your Bubble." Like its boat counterpart, it is made out of blown bubbles.
This new type of transportation had only been appeared once, in which Officer John Slugfish had been riding instead of his regular mechanical version. Unlike the Bubble Boat, the bubble motorcycle does not contain a cushion to step on for acceleration and instead is steered like regular motorcycles.
The entire motorcycle is made of bubbles from the seats, exhaust pipes, engine, and everything else. There is a flashing tail light and siren at the back of the motorcycle that goes off whenever Officer John Slugfish pulls someone over.
Role in episode
Officer John Slugfish pulls over and confiscates Mrs. Puff's boat because bubble boats became so popular that regular boats became outlawed.
