The She Creature is a mermaid entity living in Carl's pool in order to help pay his debts with the local mob. She is the last of the "fish people" after their civilization is killed when Frylock and Meatwad clean the pool with chlorine. Carl, Frylock, and Meatwad all die after she plants her eggs inside them by disappearing inside their penises and giving them an 'indescribable pleasure beyond all description', followed by a very bad itch and then exploding as the eggs hatch. When Master Shake boasts of sleeping with her and her 'friend', she encourages Terry to cut him down with a chainsaw.
