Captain Scarfish resembles Patrick Star, with the exception of a dark red scar on the right side of his face (which is revealed to be a tattoo). He wears a dark blue naval captain uniform. He wears a hat which has an "S" on it. It resembles his name, Scarfish.
He is extremely hot-headed and especially aggressive towards Mr. Krabs. This was due to the latter cooking delicious food for the ship's crew, which Scarfish was against, therefore forcing Mr. Krabs to create disgusting food for the navy crew.
This proved to be a mistake on her part, as his crew would be too weak for an ambush by pirates.
Role in episode
He first appears in the flashback as he enters Krabs' kitchen and asks him the type of food he made. Mr. Krabs reveals it to be a cucumber sandwich with the crust cut off. This angers Scarfish, as he told Mr. Krabs that on his ship, crusts are not meant to be cut off but eaten instead and tells Krabs time after time to stop making the food good, even warning him that if tonight's meal is any good, he will send Krabs to the brig.
Later during dinner time, Scarfish goes to inspect to see if the food is slop (which the sailors made it look like). He accepts but when he discovers that Krabs had actually made another good meal, he sends him to the brig to be watched by two guards.
During Krabs' time in the brig, Scarfish feeds the sailors the leftover crust to toughen them up, only to give them food poisoning.
