Reg (Presumably short for Reginald) is the official Bouncer for the Salty Spitoon. Reg lets people into the men’s bar by the showing Reg how tough they actually are. He lets Sandy in but SpongeBob is not able to enter because he is a pipsqueak weakling.
Reg is a Brown, Muscular fish with purple lips and a green headband. Reg is also bald on his 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 tatto off Reg's chest and replacing it upside down in the place of the original tatoo.
