Pi'illo Castle

Pi'illo Castle is a castle in the middle of Pi'illo Island. It used to be the home of the Royal family of the Pi'illos, but is now used a hotel for visitors of the island. The castle is made of grey stone and has a yellow roof. There are green vines growing all over the outside of the building. Just above the entrance is a stone symbol of the Pi'illo and bellow that is a pink symbol of the Zeekeeper.

Inside the castle, the floor made up of stone tiles. In certain areas the floor is covered in a pink carpet decorated with a diamond pattern.

The entrance leads to a large lobby room, that is connected to many other rooms. Behind the lobby is a locked room. In this room is a wooden platform. Stepping on the platform causes it to travel, propelled by rockets, down a steel track. The track is a long straight line and takes users into the cave hidden behind the castle. The cave has a similar flooring and carpets to the castles, the main difference being that the carpets are blue.

The castle has many rooms. One Room is used for Brock workers go to get dressed into Zeekeeper looking costumes. Another contains a Item shop, Gear shop and a  Badge Shop. There is a room with fancy looking bed and many historical items. Luigi slept on this bed to go to Dreamy Pi'illo Castle during the events of Mario & Luigi: Dream Team. Many of the other rooms are used as bedrooms for various guests. The battle ring, can also be found in the castle.

Mario & Luigi: Dream Team
During the events of Mario & Luigi: Dream Team, Mario, Luigi, Princess Peach, Toadsworth and a some Toads traveled to Pi'illo Castle.

Inside the lobby they meet Starlow, who had travelled to island to represent the Star sprits. Starlow commented on how run down Luigi looked. Broque Monsieur, suggested Luigi should use the Mushroom that he won for participating in the Coin-Up Challenge, to heal himself. Starlow decided to travel with Mario and Luigi.

Mario and gang were then given the chance to explore the castle, before visiting Broque Monsieur and entering the locked room behind the lobby. In the room they watched a video of Dr. Snoozemore on a large screen. The video gave a brief history lesson on Pi'illo Island.

Then Peach and Toadsworth climbed up on to the platform in front of the screen. The screen retracted and the platform traveled down the steel track into to the cave behind the castle. The platform returned back down the track, empty. Mario, Luigi and Starlow got on the platform to try and rescue Peach and Toadsworth.
