At the beginning of Delectabubbles, Rudie was seen browsing inside one of the doughnut cases.
The building itself is shaped like a bunny, with the soles of it's feet having windows and the stomach being the entrance. The bunny itself is holding a large doughnut.
The interior has a seating area made out of doughnut themed furniture including tables and chairs. A large doughnut acts as a doughnut case and the cashier's counter. The walls are painted with the colors of a doughnut with chocolate icing and little brown spots.
