Zip Your Fly! is the 7th episode from season 5 of The Grim Adventures of Billy & Mandy.


Grim has his clothes dirty and to take them off he uses a zip. Unfortunately, the zip does not work so Grim leaves the room keeping the zip on the table. Billy uses it to create mischief like replacing his hand with the face of milkshakes. Mandy takes it from Billy and created chaos with making Mindy lose her mouth so she can't talk and taking back Mandy's lunch from Sperg but instead feeds him Irwin to his stomach until she cut her head off to scare Billy. A fly came and sat on the zip, resulting Mandy's head replaced with Fly's body and Mandy's body replaced with Fly's head. Many drops the hook of the zip as it was heavy and seeks Grim. Harold catches her and tries to flush her in the toilet until Grim came and saw what`s happening. He and Mandy comes where she dropped the hook but finds it to be moved to the Dumping Ground. Mandy had to eat all the garbage in order to find the hook. At last they make everything normal again.
