He has the same form as Plankton, but has a black afro and sideburns, a gray mustache, a brown suit and trousers, a light yellow undershirt, a red bowtie, a pair of black shoes, and a gray briefcase.
He arrives at SpongeBob's house offering Gary a one night stay at Club Shell. He then offers to give Gary a temporary shell to replace his dirty one, which he accepts. Gary leaves, and Plankton takes off his disguise, and disguises himself as Gary, to steal the Krusty Krab formula.
His last name comes from his made-up occupation, as the owner and operator of the fictional company, Super Shell Cleaner Vacations Unlimited.
