Cas is a beaver and seems to be a friend of Ket's. His outfit is a open orange puffy vest and a pair of denim hot pants (which appear to sport a good bulge), with extra thick round glasses over his eyes.

He lives on the other side of the Southeast Beach in a log cabin, which is full of dakimakura–or body pillows–of Isadora, who appears to be a slim-looking lizard with a huge cock. He's most likely an otaku, given he's quick to fluster, has a range of posters and aforementioned body pillows, and has a cliche nerdy look to him.

He helps out Joe by lending him his “Ass Masters” book, enabling him to slam downwards with his rump.
