The Tart Toter is a Candy Person who used to work for Princess Bubblegum, delivering the royal tarts to the Back-Rubbing Ceremony at the Royal Congressional Hall. His role as the official tart toter came to an end because he went "mad - and old." It is unclear if other toters have delivered tarts since his mental deterioration. In "The Other Tarts," Cinnamon Bun offers to take his place, but Princess Bubblegum allows Finn and Jake to tote the tarts saying that Cinnamon Bun is "half-baked." Despite no longer being the official tart toter, the Royal Tart Toter arrives at the Back-Rubbing Ceremony without warning. His appearance seems to frighten the Candy People, who hide their presence from him by freezing in place (as he can only sense movement). He then gave an eloquent, if non sequitur, soliloquy to end the episode.
He makes a brief appearance as one of the guests in "Holly Jolly Secrets Part II." He also appears (wearing an Elizabethan collar) in "Princess Cookie" as a patient of the Candy Kingdom Mental Hospital.
The Royal Tart Toter is a large gingerbread man whose appearance has suffered physically as a result of his insanity. He has been bitten on the right shoulder, hip, and right leg; several of his teeth are missing, and his elaborate frosting, once ornate, has smeared in many places or vanished altogether. Several of the medals with which he was decorated earlier in his career have been lost or damaged. In his left hand he carries a chicken, and in his right hand, a squirrel. When the Royal Tart Toter speaks, icing pours out of his mouth uncontrollably, analogous to the frothing maw of a rabid animal. He is also missing his right boot. For hair, he has a pad of melted butter, and wears a shriveled Maraschino cherry for a hat.
Ladies and gentlemen, the royal tarts have arrived!
Hello? Eat my tarts?
This cosmic dance of bursting decadence and withheld permissions twists all our arms collectively, but if sweetness can win, and it can, then I'll still be here tomorrow to high-five you yesterday, my friend. Peace.
- The Tart Toter's soliloquy fits the definition of mumbo jumbo 
- His chicken is yellow in the episode "Princess Cookie."
- The bite marks on his body are self inflicted. The pet cone around his neck in the episode "Princess Cookie" is used to prevent self-harm.
- In the model sheet for "Holly Jolly Secrets Part II," his frosting is pink, but in the episode itself, it is its regular color.
- The Tart Toter has made multiple cameos in the Adventure Time comic book, including one in issue #22 where he is depicted as a clerk in the checkout line in the Grocery Kingdom.
