Mario's castle

Mario's Castle is a castle that is owned by Mario. Wario steals this castle during the events of Super Mario Land 2: 6 Golden Coins. Wario transforms the castle into a huge death trap, with tons of obstacles.

Inside are metal spiked balls, Piranha Plant statues that spit fire, and Giant Gloved Fists (Wario's gloves, to be exact) that try to punch Mario if he comes too close. Extremely odd creatures live here; one of them (actually a species) is a type of bouncing ball with Wario's face on it. If Mario beats Wario, the spell is broken and the castle turns white instead of black (and its "M", turned upside down to resemble a "W", is moved back into its correct position).

In later games, Mario's Pad replaced the castle as his place of residence in the Mushroom Kingdom.

In Mario Party 8 on Koopa's Tycoon Town, if the player gets a three-Star hotel after he or she trades coins with a Koopa Troopa at a hotel, the hotel will look like Mario's Castle.
