Angry Jack is a green fish and the manager of Angry Jack's Shell Emporium who only appeared in the episode, "Shell Shocked." He is actually a kind person who makes his commercials louder/better by being angry. However, when SpongeBob accidentally destroyed all the shells in his store, Angry Jack had "Blistering Fury."
He is light green in color and wears a white shirt and a dark pink tie with brown pants. Angry Jack, with his loud voice, spoofs many pitchmen, such as Billy Mays, who usually speaks very loudly to sell the product that he is advertising.
