Pappug's Mansion
Pappug lives in a mansion in Gyoverly Hills due to his wealth and fame from designing the Criminal clothing line. On the exterior, it looks like a giant seashell. It has a Criminal clothing store on the first floor. The prices of these clothes are apparently very high. According to a store clerk, 10,000 is below half of the original price. Keimi usually travels there to bring Pappug orient clams.
