This world introduces red Kong Switches, which can only be activated by the Super Duper Simian Slam.
Although it is unknown who created the castle and why, the structure floats high above the ground can only be accessed via a gigantic barrel cannon outside of K.Lumsy's prison. Since the level is so high up, falling off of the edge while wandering the castle grounds will result in an immediate death. The castle and grounds house a number of challenges for the Kong Family to overcome, along with an array of King K. Rool's henchmen to make things even more challenging. In keeping with the haunted theme of the level, the Kremlings and enemies who prowl the castle grounds are generally based on the undead, particularly the Bone-Kritters and ghosts who still continue to serve the Kremling Krew even in death.
The level is divided into many different areas, both within the walls of the castle and outside them. A constant storm rages outside of the castle, and the grounds have a number of interesting locations, including a large tree and a mysterious greenhouse, both of which were used to hide Donkey Kong's golden bananas. The castle itself houses a number of rooms, including a haunted library, a regal ballroom, and a museum housing different works of art (among these are paintings of Kaptain K. Rool and stone statues of unknown origin). The lower levels of the structure are home to a series of labyrinth-like catacombs, where undead Kremlings and ferocious bats live. The catacombs also home to a Mine Cart track, haunted by the Resident Demon, who attacks anyone brave enough to intrude into its domain and will take their coins. Donkey Kong needs to collect at least twenty-five coins to beat the Ghost Train Ride.
- Puftup (during the boss battle)
- Ghost Book
- Candy's Music Shop is much larger in size than it appears in any other world it appears in. In fact, it's tall enough that it's impossible for the Kongs to reach the top of the entrance's canopy.
