Koopa's Shop is a shop located in the western part of Koopa Village in Paper Mario. It is run by a Koopa Troopa. Goombario's tattle on this Koopa Troopa states: "He's a Koopa Troopa merchant who sells goods. He also checks and buys stuff. You might want to buy some stuff from him if we're going somewhere dangerous."
