The Grim Adventures of Billy and Mandy

Zip Your Fly!/Puddle Jumping

In "Zip Your Fly", a "wardrobe malfunction" on the part of a magic zipper causes Mandy and a fly to switch heads with one another. In "Puddle Jumping", Billy, Mandy and Grim have fun with an enchanted kiddie pool that has the power to transport them to other bodies of water in alternate dimensions.
