Lumpy Space King makes his first appearance in "Trouble in Lumpy Space." He is Lumpy Space Princess's father and the husband of Lumpy Space Queen. In the episode, he is seen driving home and yelling at his daughter for bringing smooth people into their world. He later bans Lumpy Space Princess from using the family car because she yelled at her mother. He seems to refer to LSP only as "daughter." He also makes a brief appearance at the end of "The Duke," during the Grand Meeting of Ooo Royalty, and in "The Eyes," dancing at LSP's quinceanera. He appears to be over-protective and strict. He once referred to their car as "the royal car" when there is nothing noticeably special about it.
His appearance is that of a purple Lumpy Space Person with black-rimmed glasses and a green striped tie (Tie used in concept). Like LSP he has a star on his forehead, which probably represents royalty in Lumpy Space. This may also be a kind of indicator that his floating powers are active, because when LSP "turned off" her floating, the star turned dark. He is conjoined with Lumpy Space Queen, The reason for this, is because when Lumpy Space People marry, they become fused together.  In "The Monster," he appears with a new appearance and personality in which he is on Lumpy Space Queen's side. In this episode, Lumpy Space King has a crown on his head, where in other episodes, he doesn't have one on.
Daughter! Have you brought smooth people into our domain?!
You've made your mother cry for the last time, daughter! You are hereby banned from using the royal car!
