Sherbet's basically a vital form of IC Tessie, or at least somewhat, from beyond the fourth wall that seems comfortable in both OOC and IC dimensions. She's even more of a bitch than Tessie it seems, what with the pickle obsession and all, but she has a good heart. She's basically a cat, with some kind of hair, it seems. Nobody knows her history, or where she came from, nor why her last name is so.
Blah blah blah.
She doesn't really know anything Tessie does, and really shouldn't have Redbull, because she drinks a whole package.
