Angry Jack's Shell Emporium is a shell emporium that sells snail shells, owned by Angry Jack, who is not actually angry, he's just trying to sound angry to "reduce his inventory. SpongeBob owed Angry Jack money (because he broke all the shells in the emporium), but he only had change, so Angry Jack took his arm, kidney, an eye, and his clothes.
Angry Jack Shell Emporium sells different types of shells. The store has at least one advertisement in the paper. SpongeBob saw the commercial on television but somehow interrupted Angry Jack during the commercial. Scooter and Angry Jack are the only people in the commercial.
