The Popcorn King is an item that appears in a few episodes of Ed, Edd n Eddy. It is a popcorn maker. Its first appearance was in "Ready, Set... Ed!" as the false engine for the Rocket Car. It ended up overheating when Kevin put too many kernels in, and it sent the car flying onto the World's Scariest BMX Ramp in a large popcorn explosion.
It also appeared in "Little Ed Blue" during the screening of "The Hunt for Edosaurus" as the popcorn machine Eddy was using to serve the kids, suggesting that Eddy repossessed his machine after it was used against him.
