|Voiced by||Dee Bradley Baker|
Cinnamon Bun is one of the Candy People living in the Candy Kingdom. He has a very short attention span and does not think clearly, but seems to have unrestricted access to the castle. He also resembles an old man as of his voice and mouth wrinkles. He has a mouth on his chest which is where he swallows his food.
He first appeared (with green eyes) in "Slumber Party Panic" in the crowd of candy people.
In the episode "The Enchiridion!," he is shown to be very clumsy as he attempts to do a backflip and stumbles backwards and crashes into a tall tower with Princess Bubblegum in it. In this episode, Cinnamon Bun has green eyes, but in all future episodes, his eyes are black and similar to Jake's. Cinnamon Bun has a very nasally voice and is possibly not very highly regarded in the Candy Kingdom.
Cinnamon Bun also makes an appearance in "Power Animal," where he tells Jake that he can't focus on anything. Jake tries to prove him wrong, but fails. Instead, Jake saves Finn by being an "unfocused, rowdy party-dog" and makes the suggestion of eating Cinnamon Bun, but they never do.
In "The Other Tarts," he was originally offered to be the bringer of the Royal tarts to the Back-Rubbing Ceremony, but Princess Bubblegum could not trust him due to his erratic behavior, referring to him as "half-baked." Finn decides to use Cinnamon Bun anyway, giving him what he thought were decoy tarts to take along the tart path to the ceremony while he and Jake took what he believed to be the real tarts through a dangerous path called the Desert of Doom. Ultimately, it was Cinnamon Bun who had the royal tarts which were transported safely while Finn took the paralyzed tarts that were stolen by various thieves and monsters.
Cinnamon Bun again appears in "Conquest of Cuteness." He is in Finn and Jake's army to be defeated by the Cuties, along with Lumpy Space Princess, BMO, and an unnamed duck. When Finn squirts ketchup on him as fake blood he starts to lick it off of his face, but pretends to be dead like the others in the end.
Cinnamon Bun appears very briefly in "Too Young." He is fooling around on a swing inside Princess Bubblegum's Castle and falls. The Earl of Lemongrab arrives in the castle and commands that the castle be cleaned up, or they will be thrown in the dungeon.
In "Fionna and Cake," there is a genderswapped version of Cinnamon Bun wearing a green dress and talking to Prince Gumball at his ball.
In "The Creeps," Cinnamon Bun is invited to the spooky party and instructed to use the name Guy Farting. He was dressed in an emerald green suit, bow tie, top hat, a pink and magenta striped shirt, a large black mustache, and a monocle. A note from the party's host was taped to his back. He revealed that he may have a crush on Lumpy Space Princess, saying "Now's my chance" after finding out that her and Brad broke up. He was also the first guest to be killed.
Cinnamon Bun was in "Holly Jolly Secrets Part II" very briefly. He was sitting on the floor and wearing a blue sweater, scarf, and gloves.
In the episode "Five Short Graybles," Princess Bubblegum fed him the perfect sandwich.
In "Dream of Love," he helps Princess Bubblegum to carry the keyboard and said to the Candy People that the event was over, showing a more aggressive side.
He is one of the Candy People who is disappointed with Finn's hugging in "Hug Wolf." He is the first known victim of Finn and the one who let Finn escape from his cell.
Cinnamon Bun is seen in "Davey," while Finn (disguised like Davey) has a tour around the Candy Kingdom.
At the beginning of "All Your Fault," Cinnamon Bun is seen having a dress-up play with Jake (with Jake being dressed up like a woman, a bow on his head). However, the game is interrupted by Finn and Jake's new task. While they're leaving, Cinnamon Bun waves with a napkin (similarly to how women wave farewell in older movies) and yells, "Goodbye, girlfriend!"

You came into my room around midnight and gave me a squeeze... A really strong one!
