Reginald is the bouncer (entrance guard) for the Salty Spitoon. Reg lets people into the club by showing him how tough they are. He lets Sandy in but SpongeBob isn't able to enter because he's not tough enough.
Reg is a brown, muscular fish with purple lips and a green headband. Reg also has a bald head. He has a tattoo of a heart that said MOM but Sandy, who was trying to show how tough she was, turned it into "WOW" by ripping the tattoo off Reg's chest and replacing it upside down. He also makes a few cameo appearances in later episodes.
- He is voiced by Tom Kenny.
- Reg first appeared in No Weenies Allowed and also appeared in Shell of a Man and Krusty Krushers, but appeared yellow.
