Role in short
Man Ray steals Mermaid Man's starfish mask, but gets caught and is about to be covered with tartar sauce. It is then revealed that Patrick had eaten the remaining tartar sauce. Afterwards, Man Ray captures Mermaid Man and Barnacle Boy and is about to obliterate them, when Super Tightwad flies in and dumps another bucket of tartar sauce on him.
Super Tightwad then frees the two heroes and charges them a bill. Not having enough money, Mr. Krabs makes Mermaid Man and Barnacle Boy work at the Krusty Krab.
"They call me Super Tightwad, here's me bill for services rendered."
Super Tightwad's name is similar to Captain Tightwad. They are also both played by Mr. Krabs.
