Lumpy Space Princess, or oftenly called LSP, is the princess of Lumpy Space. She is the next most recurring princess next to Princess Bubblegum.
LSP is actually a hobo proved at the episode, The Monster and To Cut A Woman's Hair. This episode occurs that LSP says she can take care of herself. Due to her stubbornness, she left her comfortable house and lived with wolves.
Name: Lumpy Space Princess
Family: Lumpy Space King (father), Lumpy Space King (mother)
Lumpy Space Princess acts similar to a bratty, apathetic, attention-seeking and willfully ignorant teenager.
Lumpy Space Princess can be ostensibly unmoved and uncaring about what goes on around her, using such words as "sure," "whatever," and "fine" frequently. She can also be physically apathetic and unwilling to make an effort, as shown in Gotcha! when she reluctantly helped Finn and Jake carry rocks, but complained the entire time (even though it was only two small rocks).
Lumpy Space Princess looks like a cloud and speaks in a somewhat masculine voice, like most Lumpy Space People. Lumpy Space Princess also has sharp teeth as well as a yellow star on her forehead that glows while she is floating. There appears to be short hair on her body, which she claims to be more of her "lumps." When she punches herself (saying she can be "smooth"), she looks like a ball with arms. She is not seen wearing a crown, like most other princesses; however, the star on her head probably represents royalty, given that the only other Lumpy Space People with that characteristic are her parents. The star on her head is actually a jewel that goes very deep into her. When using all the jewels collected to open the Enchiridion book, Lumpy Space Princess' star jewel is the only jewel not able to be used.
