Lumpy Space Princess, often abbreviated as LSP, is the princess of Lumpy Space, an alternate dimension. As a "Lumper", made out of "irradiated stardust", she can convert other beings into Lumpers by biting them. LSP is spoiled and sarcastic, and is often shown living outdoors with salvaged furniture and appears to be homeless, because she has run away from her parents, who are the king and queen of Lumpy Space. She speaks with a thick Valley Girl Accent. LSP's relationship to Finn and Jake has always come off as nonchalant, but in the episode "Gotcha", LSP realizes that Finn is a person of good moral standing who teaches her that beauty comes from the inside, and in her premiere episode, she reveals to Finn that he's supposed to be her real friend, not like the "fake" ones she has in Lumpy Space.
