Lumpy Space Princess

Lumpy Space Princess (or LSP) is the princess of Lumpy Space. She is the second most recurring princess after Princess Bubblegum. Finn and Jake have both traveled to Lumpy Space as well as to her (parents') residence after she accidentally bit Jake in "Trouble in Lumpy Space."

Since "To Cut a Woman's Hair," LSP moved out and has been living homeless in Ooo. She was shown as a dirty homeless girl living in a tent and heating up a can of beans in "Heat Signature." According to her story in "The Monster," she lived among wolves, was banished, and later began terrorizing a small village as a "monster" in order to eat their crops. She ultimately returned to Lumpy Space to make up with her parents.

Appearance
Lumpy Space Princess looks like a floating purple cloud and speaks in a somewhat male voice, like most Lumpy Space People. LSP also has sharp fangs as well as a yellow star on her forehead that glows while she is floating. There appears to be hair on her body, which she claims to be more of her "lumps." She is not seen wearing a crown, like other princesses; however, the star on her head may represent royalty, given that the only other Lumpy Space People with that characteristic are her parents.

Abilities
Like most Lumpy Space People, she has no legs or feet, but can float. Also, she can infect someone with The Lumps if she bites a non-lumpy person ("It's like, werewolf rules"). She can choose not to float if she wishes. This is shown in "Trouble in Lumpy Space," during the Mallow Tea Ceremony. As the yellow star on her head grew dim, she began to be influenced by gravity, fell, and accidentally bit Jake.

Personality
Lumpy Space Princess acts like a stereotypical bratty, teenage girl. She tends to lose her temper and make fun of people, but she can still be nice towards others. For example, in the episode "Trouble in Lumpy Space," she tried to assist Finn in his adventure of finding the cure for The Lumps for Jake. Also in "Mortal Recoil," she was there at the hospital for Princess Bubblegum, indicating affection and sensitivity, and cried when Finn lashed out at her when she insulted the "smooth posers," but she forgave him by asking him to dance when Finn apologized afterwards. She often misunderstands things and is quick to anger, as shown in "It Came from the Nightosphere," when she became upset with Hot Dog Princess for going to a "party" to which she wasn't invited. Her best friend is Melissa, a pink lumper who is currently dating Brad, her ex-boyfriend. Also, in "Trouble in Lumpy Space," she asks Finn to make room for her in the back seat of Melissa's car, due to the fact that there would be a lot of romantic tension because Brad and LSP used to eat chili cheese fries together. LSP can be ostensibly unmoved and uncaring about what goes on around her, using the words "sure", "whatever", and "fine" in no short supply. She seems to have a strained relationship with her parents, apparently swearing at them, using such expletives as "Lump off." This makes her mother cry, causing her to be banned from the royal car. Angered at her inability to help Finn and Jake without the car, she calls her parents "horrible idiots." This isn't the only indication that LSP is a teenager. She also went to a "promcoming dance," (which is thrown weekly), suggesting that she is in an equivalent to high school. Further proof of this lies in "The Eyes," wherein Finn and Jake are seen dancing at her Quinceañera, which (in the real world) is a celebration of a girl's fifteenth birthday in several Latin American cultures. It's unclear whether "Quinceañera" has the same meaning in Lumpy Space.

LSP seems to be aware of her shallow relationships with friends in Lumpy Space, as she refers to Finn and Jake as "real friends" as opposed to her "fake" Lumpy friends. This may be why she spends so much time outside Lumpy Space with the other princesses of Ooo. She has a relationship with Hot Dog Princess, as shown in "It Came from the Nightosphere." In "To Cut a Woman's Hair," LSP is shown to have run away from her parents and set up camp outside in the woods. In "Heat Signature"—she is shown cooking a can of beans in a makeshift camp—until "The Monster," when she realizes her mistake and moves back in with her parents.
