Pilaf's Castle was once Emperor Pilaf's main residence. It was located in the Diablo Desert and was turned into a pile of rubble by Goku when he looked at the full moon and became a Great Ape. The castle was built by one of Pilaf's older ancestors.
The first floor of the castle is a dark maze filled with many traps and can be viewed by Pilaf in his control room. There is also an entire room that is a giant pinball machine, which is a trap for intruders. Pilaf has his throne room where he eats and is visited by Shu and Mai to report him their failures. There is apparently only one bedroom that all three of them share, as all three of their beds are in the same room.
The castle has also a hangar where airplanes are launched and a weather control device above it for Pilaf to make a thunderstorm happen to shock Shu and Mai after they fail their missions. Pilaf even has a giant incubator where he keeps prisoners to die out in the heat. The castle has been seen to be patrolled by Shu's pet wolves.
