It is a bike-shaped bubble with two seats. There is also a basket for the Krabby Patty to be stored in.
It was used by SpongeBob and the player in an attempt to get to "Patrick." When they go through Bikini Bottom, SpongeBob tries to think of what Patrick would think, which makes him stop controlling the bike and have it go through town in a dangerous way. When SpongeBob rides the bike through Jellyfish Fields, he sees Patrick with the pickle, but cannot reach him. When SpongeBob and the player fall down to Rock Bottom, the bubble bike explodes from the creatures living down there, sending them into the air and into the Chum Bucket.
