He is a light beige colored fish with dark tan lips. He wears glasses, a dark orange hat and light orange shirt and dark blue overalls.
He was seen painting signs in "Lost in Bikini Bottom" when SpongeBob appeared at the Krabby Krust. SpongeBob then asks him if he can tell him how to get to the Krusty Krab from there but Sal claims he has never heard of the Krusty Krab. SpongeBob then gives him coupons to the Krusty Krab and he drives there, leaving SpongeBob behind. He is seen at the Krusty Krab at the end of the episode, showing Mr. Krabs the coupons he got.
