Cinnamon Bun resembles a large brown bun that has a gooey face due to being half-baked. He has small black eyes, but they appeared large and green in "Slumber Party Panic" and "The Enchiridion!" His mouth is misshapen and full of crooked teeth. Before "The Red Throne," Cinnamon Bun had a wrinkly texture that gave him a slightly elderly appearance. After being blasted by fire, he becomes fully baked and attains a dry, smooth face.
Cinnamon Bun, like most Candy People, doesn't wear any clothes. However, in "The Creeps," he puts on an emerald green suit, bow tie, top hat, a pink- and magenta-striped shirt, a large black mustache, and a monocle. He also has a note from the party's host taped to his back. Also, Cinnamon Bun wears a blue sweater, a scarf, and gloves while making a brief appearance in "Holly Jolly Secrets Part II." In "Apple Wedding," he wears a sapphire suit, midnight bow tie, and a light blue colored shirt.
Currently, Cinnamon Bun wears a cone with fire sprouting from the top and has blue skin due to a spell protecting him from the Fire Kingdom's heat. He either carries a staff with a fire on top or a lance. In "Princess Day," with Flame Shield on, he was dressed as a Flame Knight and had fire floating on the top. He also wore a band around his head, holding a fire gem in the middle. He is seen wearing this knight outfit again in "The Cooler". In "Jake The Brick," he is seen wearing a robe.
In "Fionna and Cake," the gender-swapped version of Cinnamon Bun looks almost identical to her male counterpart, the only distinguishing features being her green dress, bow, shoes, and eyelashes.
- Dee Bradley Baker voiced Cinnamon Bun in the TV series. He returns to voice Cinnamon Bun in the game.
- He is the only Year 2 Citizen in Peril who couldn't be saved using the packs at the time of the level's official release as he requires Raven's Raven Portals Ability which is included in Wave 9.
