The Sky Kingdom (空中公園, Kūchū Kōen, Air Park) is an area accessible from one of the paintings in the Art Gallery and from the Apartments.
Features
The kingdom contains floating red, yellow and blue tiles that serve as the floor, along with various plants and flowers. There are some colored panels that can change color when interacted with. There is also a bench that you can sit on and a vending machine. Near to the bench area is a path that leads to Ecstacy World.
If you enter from the Apartments, you need to get past the moving guards to open the door. You do this by simply chainsawwing them, however they move faster when you equip the effect. Instead of screaming as usual, they make a whistling noise when killed. After you've killed them, you can get to the other side.
The creatures that inhabit the world are mainly people that resemble Teletubbies and moving puddles with faces on them. There is also Dogboa (a dog version of Uboa from Yume Nikki), who you can see across the ledge with the dog sign on it, moving quickly in a sectioned-off area.
