Lumpy Space Princess

Lumpy Space Princess a.k.a. L.S.P, is the princess of Lumpy Space. She is an important minor character, as she is seen in multiple episodes. She has accidentally bitten Jake, making the basis for Trouble in Lumpy Space. She is the second most popular princess, after Princess Bubblegum. In the episode Ricardio The Heart Guy she is seen being massaged by Ricardio. She sometimes uses the word "lumpin", or "lump", in place of profanity, which is probably profanity (it is likely to be slang for the way lumpy space people are made) in Lumpy Space, as her parents are horrified when she says "lump off". Lumpy Space Dad and Lumpy Space Mom are her parents. Although her voice does not sound too feminine, she is in fact a girl, as confirmed by her title.

Appearance
Lumpy Space Princess looks like a floating purple cloud, like most Lumpy Space People. She also has a yellow star on her forehead and sharp fangs. She is not seen wearing a crown, like the other Princesses. However, the star on her head may represent royalty, seeing as that the only other characters with that characteristic are her parents.

Abilities
Like most Lumpy Space People, she has no legs or feet, but can fly. Also, she can give someone The Lumps if she bites a non-lumpy person. She can choose not to float if she wants to. This is shown in the episode Trouble in Lumpy Space, during the Mallow Tea Ceremony. The yellow star on her head grows dim, and she experiences the full effect of gravity. She then falls down and accidentally bites Jake.

Personality
Lumpy Space Princess acts like a completely normal teenage girl. She tends to lose her temper and insult people, but she can still be nice towards others. For example, in the episode "Trouble in Lumpy Space", she tried to assist Jake in his adventure of finding the cure for The Lumps. She's pretty sensitive, and cried when Finn lashed out at her when she insulted the "smooth posers", but she forgave him when Finn apologized afterwards. Her best friend is Melissa, a pink lumper, who is currently dating Brad, her ex-boyfriend. She can also be very unmoved and uncaring as to what is going on around her, using the words "sure", "whatever", and "fine" very often. She seems to have a strange relationship with her parents, apparently swearing at them and, eventually, making 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 may only contribute to the fact that LSP is a teenager. She also went to a prom coming dance,(which are thrown weekly) which hints that she may be in high school, but it is still unclear.

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 other princesses of Ooo.
