Lumpy Space Princess is one of the three most recurring princesses, the other two being Flame Princess and Princess Bubblegum. Finn and Jake have traveled to Lumpy Space as well as to her parents' residence after she accidentally bit Jake in "Trouble in Lumpy space". According to the events in "Princess Day," she is not recognized by the chair of princesses partially because of her dramatic attitude.
