Las macabras aventuras de Billy y Mandy

Grim decides to make a cake for Billy's birthday, but he and Mandy end up making a Devil's Food cake that comes alive and began wrecking the kitchen. The cake hops on Grim's face but Mandy smashes it and splatters it all over the kitchen. Grim and Mandy give Billy a cake covered kitchen, much to Billy's delight.
