Grish, otherwise known as Grish the Beautiful, is Nick's Planet Sheen counterpart and Princess Oom's two-headed ex-boyfriend. Each of Grish's heads has a mind of their own. Sheen often tries to get him and Oom back togehter, but he keeps failing, no matter how hard he tries. Even when Sheen tells Grish that he doesn't want Oom, he still threatens to pound Sheen for rejecting the woman he loves.


Grish has brown-orange skin. Each head is identical: blonde hair, two eyes on short stalks, large pointed chin, and a mouth with many teeth. Grish has a huge muscular body. He wears a red shirt with a white collar. His pants are blue, and his shoes are brown.
