Reg is the entrance guard for The Salty Spitoon. He lets people into the club by showing him how tough they are.
Reg is a light grayish brown, muscular fish with light purple lips and a green headband. Reg also has a tan bald head. He has a tattoo of a heart that says MOM, but Sandy, who is trying to show how tough she is, turns it into "WOW" by ripping the tattoo off Reg's chest and turning it upside down.
Reg serves as a bouncer for the Salty Spitoon. He lets Sandy in after she proves herself tough enough by ripping off his tattoo and putting it back on upside down, but doesn't let SpongeBob in due to being far too weak.
Near the end of the episode, he grants SpongeBob entrance after he fakes a fight with Patrick.
