4x19 - Courage the Cowardly Dog

Ashamed at what happened to her husband, the wife of the Chicken from Outer Space sends their three-headed son to destroy Courage. When they land, they try to just zap him, but they hit Eustace instead. Then they tried a bomb disguised as an egg, but Courage puts it in the toilet, and blows up Eustace. And they finally try tieing Courage up and running over him with a train. The three-headed chicken fails and starts getting in a fight with itself. They start crying because it's mother said that if they don't kill Courage, they can't come home. The middle head always carries a camera, so Courage has them take pictures of Courage being tortured. With that, the chicken bades farewell, but Eustace, Muriel, and Courage end up looking like a three-headed chicken.
