Cerebrocrustaceans (a play on "cerebrum" and "crustacean") are an extraterrestrial species of very intellectual crab-like arthropods from the stormy planet Encephalonus IV. Their ancestors took advantage of the natural storms surrounding the Encephalonus planets and it in turn resulted in the destruction (by using up all natural resources) of the planets Encephalonus I through III by the time they arrived at Encephalonus IV they had evolved in order to create the electricity instead of taking it away and therefore arrived as the electricity generating crustaceans you now see. They are deeply ashamed of their ancestors being responsible for the destruction of their original homeworld Encephalonus I and the two other planets in there solar system.
