Cow and Chicken Season 3 Episode 20

Intelligent Life?

Cow doesn't wish to come in, but rather stay out all night to stare at the moon. So she builds a make-shift rocket ship out of cardboard boxes, a trashcan, and traffic cone. It ACTUALLY works, and finds herself on the planet Mud, where she brings space alien (Red Guy) back to earth where he says the solution to all problems is: puppets.
