Lumpy Space Princess (also known as LSP) is the Lumps anti-Elemental and reincarnation of Lumpy Space Princess inhabiting 1000+ Ooo. She first appeared in the background of the opening of "Come Along With Me," staring at Shermy and Beth in the ruins of the Candy Kingdom.
Lumpy Space Princess is a small, pink/purple Lumpy Space Person with tiny arms and legs. Like her past incarnation, she has a star shaped gem embedded in their head. The top of her head has two lumps that resemble a butt.
- She is one of the only Lumpy Space People seen with legs, the other being Brad. Unlike Brad, she seems able to float.
