Mr. Cupcake is a character who appears in "Slumber Party Panic," and he has made minor appearances in other episodes, including "The Enchiridion!" and "Evicted!," and also in the title sequence. He is one of the Candy People, and lives in the Candy Kingdom. In "Slumber Party Panic," Chocoberry dares him to take off his wrapper, revealing that he is chocolate, and no one seemed to know that he was chocolate. He is most likely friends with Finn and Jake, because he was at their party in "Evicted!." In the episode "Video Makers," Mr. Cupcake is asked by Jake to play the role of "Todd Johnson" in the movie he and Finn were making. He is cast opposite of Lady Rainicorn, who he starts to flex in front of. When Jake voices his disapproval, he and Mr. Cupcake get into a physical confrontation. He appears once again in "Hug Wolf" as one of the candy people who were hugged by Finn. As of June 7, there is a Mr. Cupcake cut-out on the official site. Mr. Cupcake also appears in You Made Me when Princess Bubblegum calls for a Candy Kingdom meeting. She asks him if he would live with Lemongrab, resulting in Mr. Cupcake breaking his own arm instead of living with Lemongrab.
Mr. Cupcake appears to be physically fit. He has tiny white eyes, a brown mustache, a pink nose, and brown eyebrows. He's covered with vanilla frosting and has a few blue sprinkles on top of him. He wears only a blue foil wrapper, which covers his chocolate body.
Jake, truth or dare?
Do you prefer chocolate or fudge?
I don't hear her complaining.
- Usually, Mr. Cupcake wears his wrapper. Although, in the first part of "Slumber Party Panic," when all the Candy People are walking in to the castle, he is seen without a wrapper and you can see in that part that he is indeed chocolate.
- It is shown in the "Fionna and Cake" theme song that he has a gender-swapped version of himself, Ms. Cupcake.
- Mr. Cupcake's accent changes between his two speaking roles in "Slumber Party Panic" and "Video Makers."
- Original artwork for Mr. Cupcake had his arms and legs colored blue (similar to the shade of his wrapper), but they were changed to their current color prior to the production of the show.
