Princess Bubblegum's castle (also known as The Candy Castle) is the home of Princess Bubblegum and former home of the King of Ooo. It is located in the middle of the Candy Kingdom, between the Rock Candy Mountains.
AppearanceThe castle includes red pathways, tall, bent towers, and the central tower, which is straight and wider than the others. It is cream colored, like vanilla ice cream, and has been seen dripping. It also has a moat,that has been shown filled many times. Two large statues, called the Guardians of the Royal Promise, sit near the castle blowing bubbles, and try to protect the kingdom when otherwise needed. The castle has a drawbridge (which is a piece of toast with jam on it) in the front, and leads into a courtyard as seen in "The Duke." The castle was the location of the party in "Slumber Party Panic." One of the narrow towers appeared in "The Enchiridion!," when its watchtower was destroyed by Cinnamon Bun, who was attempting to do a back flip. It is unknown if the watchtower was rebuilt. In "Ricardio the Heart Guy," when Finn and Jake enter Princess Bubblegum's castle door, two sculptures of Finn and Jake are shown at both sides of the door, both built with a muscular body. In "Go With Me," the portcullis is revealed to be made of pretzels. The castle is surrounded by lollipops.
Numerous rooms and secret passages of Princess Bubblegum's Castle have been shown throughout all seasons of the show.
Princess Bubblegum's Bedroom
This was shown in "Mortal Recoil" when Princess Bubblegum was put in there to rest. It is pink and purple themed, and has several hearts on the wall. There are two large windows on either side of her large bed, and in front of each a small pink tree is placed. The room also contains what seems to be a computer and a glass cupboard with two crowns in it, but the rest of her bedroom consists of pink cabinets. There is also a bathroom leading off the right-hand side of Princess Bubblegum's bedroom. In the bathroom is a bathtub, sink and toilet.
The grand hall was first introduced in "Slumber Party Panic" as the "party room." It has a high ceiling, a large carpet in the front, and two large front doors. It can hold all of the candy citizens. There are shuttered windows lining the sides of the hall. There is also a closet-like room shown in "Slumber Party Panic," which Jake and Lady Rainicorn squeezed into to play 7 minutes in heaven.
Also in "Slumber Party Panic," Princess Bubblegum and Finn go into a side room adjacent to the Grand Hall to discuss the zombies. This room does not have any lights, but it is clear enough to see.
In "Slumber Party Panic," Finn and Princess Bubblegum go into another room to figure out the decorpsinator serum. This room is white, has cupboards and counters, a "science shower," supposedly for spills, and there are beakers and test tubes everywhere. There is also a chalkboard in the room. The door into the laboratory is made of "candy steel," as stated by Jake in "From Bad to Worse," when he, Lady Rainicorn, Lumpy Space Princess and Finn were trapped in the lab by candy zombies.
In "The Enchiridion!," Princess Bubblegum and Finn go into a secret room through the bottom of the Candy Castle. The room has blue glowing spots on its walls. The same room is seen in "Death in Bloom" when Finn and Jake are playing and taking care of the Princess Plant. In "Mortal Folly" it is were the princess keeps The Gauntlet of the Hero.
In "Death in Bloom," Finn and Jake enter the Land of the Dead through the nursery, the room where they leave the Princess Plant after killing it. It has a mobile, a stackable-rings toy, and other items related to child care.
(Possibly) Princess Bubblegum's tea room
In "The Duke," a hallway can be seen. It has an orange color scheme, possibly due to candle light.
The inside of the tree
Parts of the inside of the tree on top of Bubblegum's castle are shown in some episodes. The tree contains rooms composed entirely of branches and twigs, from the ceiling and walls to the floor. The walls curve smoothly into the ceiling and floors, which make the rooms look more like hollowed-out spaces in the tree.
In "Mortal Folly," Princess Bubblegum reveals that the inside of the tree stores The Lich, sealed away in amber after being taken down by the hero Billy. He subsequently escaped after possessing the waving snail, who opened a crack that allowed for its release. To prevent brainwashing while near to the Lich in the tree, Princess Bubblegum wore her jeweled crown and gave Finn and Jake their own jewels. This is also the location where the waving snail became possessed by the Lich. It was also in the tree were Peppermint Butler summoned the demon Ogdoad in a dark magic ritual in the episode "The Suitor."
In "What Have You Done?," there are a lot of secret doors and secret passages that lead to this dungeon. From this episode, Jake said "Wow, there's a lot of secret doors in this place."
In "Rattleballs," Princess Bubblegum is shown preparing eggs in a possible kitchen in her castle.
