Penps are alien cloud seals who live flying on the planet Flarbellon-7. They went extinct as a result of the explosion that took place when Rick(C-132) and Morty(C-132) first went to Flarbellon-7 to collect Penp Juice and became entangled in a fight between Barbarica and Robobros. They were later upgraded to endangered after Summer(C-132) returned and released Penps she had stolen from space zoos.
