The Incredible Shrinking Mandy is the 19th episode from season 7 of The Grim Adventures of Billy & Mandy.


As Grim cannot take any more abuse from Mandy, Billy decides to help him by using Grim's scythe to shrink Mandy. However, he messes up the spell and Mandy becomes a giant instead. She crushes Billy under her giant fist and walks away with the ground shaking under her heaviness. She destroys Billy's house and saves Billy from Sperg.

Eventually, Mandy wants to return to her normal size after seeing the inconvieniences (of having to pay a lot for 3,000 cheeseburgers and falling to the other side of the world) of being a giant. She is also still growing bigger from time to time (she finally becomes large enough to crush her house) and Billy is the only one who can change her back. However, Billy refuses to and Mandy becomes bigger than the world, and she is sent into the "Realm of the Infinite", where Mandy meets other creatures that are forced to grow bigger than the entire universe, and as usual, Mandy bosses them around.
