Missy Elliott is a fish singer for the Whale Wash station when Oscar and Mr. Sykes hosted a party at the station. She, along with the jellyfish singer, was the only ones who are known by Oscar.

[A laboratory-like tank was still on top of the whale when two doors moved.]

Oscar: Missy! Christina! C'mon outta there!!

[The doors finally opened to reveal Missy, who is a parrot fish, and Christina, who is a jellyfish like Ernie and Bernie.]
