Lumpy Space Princess

Lumpy Space Princess a.k.a. L.S.P., 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 her residence, after she accidentally bit Jake in the episode "Trouble in Lumpy Space". Though, it is believed she moved away since then.

Since the episode "To Cut a Woman's Hair", she has been in self-exile on Ooo and living as a hobo on the land. In the episode "Heat Signature", we see her campground and her preparing a can of beans for dinner. It is assumed that LSP had an argument with her parents and moved out.

Appearance
Lumpy Space Princess looks like a floating purple cloud and a man, like most Lumpy Space People. Her features do not appear, act or speak very feminine, but she is indeed a female. She also has a yellow star on her forehead which glows while she is floating, and stops glowing when she is not floating. She also has sharp fangs. There appears to be what's like hair on her body, but she claims it is just more of her "lumps". 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. Lumpy Space Princess never wears a crown but she doesn't seem to care. She can be sweet to various people such as Jake or Princess Bubblegum.

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 the stereotype of a spoiled 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, so she's pretty sensitive, 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 gets mad and misunderstands things often, shown in "It Came from the Nightosphere", when she was a little bit mad at Hot Dog Princess for going to a "party" she wasn't invited to. 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. 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 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 may only contribute to the fact that LSP is a teenager. She also went to a prom coming dance, (which are thrown weekly) which gives proof that she is in high school. Further proof of this is that Finn and Jake are seen dancing at her Quinceañera, suggesting that she is fifteen.

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. She has a relationship with Hot Dog Princess, as shown in the episode "It Came from the Nightosphere". In "To Cut a Woman's Hair", LSP is shown to have ran away from her parents and set up camp outside in the woods. In "Heat Signature", she was still homeless.
