Bumper Cars

In the episode "Gimme Gimme Never Ed" Jonny and Plank keep geting the Eds to build them rides. The bumper car ride is one their first rides. The bumper car is little more than inner tubes and a wagon. They have full directional motion which lets them function like real bumper cars. Their inner tubes allow them to potentially be amphibious, but it isn't shown.

Here is a list of all items it was made out of:

 * Inner Tube
 * Wagon (Modified)
 * Barrel (Double-D)
 * Crate (Eddy)
 * Car Seat (Ed)
