The episode introduced Flame Princess, who would become a more important character in the following seasons; the character is voiced by Jessica DiCicco. Flame Princess was written to be "clueless", in that she was emotionally more immature than any of the other characters. This allowed other, usually immature characters like Finn to play off of her in a different and unique way. The design for the character was based on a rough drawing by Natasha Allegri. This drawing was later cleaned-up by Sugar; originally, she envisioned Flame Princess as being similar in coloring to a match, with "dark skin and fire for hair". Her sketches were later redesigned for the show by Andy Ristaino. When Sugar was redesigning the character, she added a gem in the middle of her forehead, which she claimed was inspired by the rudimentary designs for the characters in her series Steven Universe, which would air several years later.
