Nightmare Head

The Stan balloon is a terrifying hot-air balloon in the image of Stan Pines' head.

History
In "The Love God," Stan and Soos Ramirez build the balloon to appeal to the youth at Woodstick in hopes of expanding the Mystery Shack's market. However, due to their inattention to safety hazards, the balloon catches fire soon after its release and terrifies the Woodstick audience before crashing into the Love God, who had been pursuing Mabel an Dipper Pines for stealing one of his love potions, thus allowing the twins to escape.

Appearance
The balloon takes the appearance of Stan Pines' head, albeit more hideous and patched and flaming. It originally bore the message "I HEART KIDS;" however, after some letters fall off, it states "I EAT KIDS," further terrifying the youth.
