The Grim Adventures of Billy and Mandy: Grim For A Day/Chickenball Z/Max Courage

"Grim For A Day" After long hours and late nights, Billy says being the Grim Reaper is easy compared to being a child. Mandy suggests Grim and Billy change places for a day and in the process find themselves each physically changing into the other. "Chickenball Z" Mandy eats a supposedly magic chickenball from the Ping Pong Dynasty in the hopes of winning a karate championship. The only catch is that the chickenball is really a ploy sent by Eris to create chaos. "Max Courage!" Major Dr. Ghastly lures Dr. Courage onto Bunny Island in the hopes of building the ultimate war machine, so that Hector Con Carne can rule the world.
