The Donut Guy is a minor character of Adventure Time that first appeared in "Five Short Graybles." He is one of the attendees to the Talent Show. He shouts "That's amazing!" when Lumpy Space Princess first bounces a basketball of the audience and makes it into the basket. Lumpy Space Princess makes her third goal in a row bouncing the basketball off of the Donut Guy's face. The Donut Guy falls out of his chair, but still happily chants "LSP!" with the rest of the crowd after her act. He next appears in "A Glitch Is a Glitch" when Finn and Jake see Princess Bubblegum he comes out of a candy house screaming "MY FACE, MY FACE!! OH MY BEAUTIFUL FACE!!" and was running around. He also seen screaming "OH MY FACE!! IT'S BACK TO NORMAL!!" when Finn and Jake were about to ask him where Princess Bubblegum is.
The Donut Guy looks like a pink-frosted donut with rainbow sprinkles. His arms are at the side of the donut and his face is on the front of the frosting, unlike Dr. Donut.
