    Concrete World is an area accessible from the Museum.

    Full Map of the Elevators


    The basic landscape of this area is constructed of orange-and-yellow blocks and grey concrete floor tiles, with a few scattered pipes sticking out of the ground.

    From the Museum's entrance, you can use the elevator on the left to get to the ground floor and explore the area.

    Along the top wall of the area is a doorway that will take you up a large tower structure made of the same orange blocks, with elevators leading to different parts of the tower. This area originally housed many things that can now be found in Flying Fish World, which replaced it in later versions. The elevators still work, but many of the places and rooms they lead to are now empty or nonfunctional.

    Close to the top, one of the mice from Toy World may be present on a cube near a doorway. At the top is a scenic path with a distant view of a city. On the other side is a large, flat roof with a strange laughing tree, as well as a frozen plant southwest of the tree, leading to Frigid Meadow, and a staircase leading to Upside-down Forest World. Visiting this area once will unlock access to it in Upside-down Forest World. The tree can be destroyed by using the Chainsaw, making it disappear until you leave the area and return. Using the Crossing effect will transform the tree into a red creature with weird eyes until you either use the effect again or unequip it. Interestingly, the creature retains the tree's hitbox despite being much smaller.

    Slightly east-southeast of the museum entrance is another doorway, leading to a large looping area known as Concrete World B. Near that doorway is a spinning gray diamond that connects to Legacy Nexus if it has been unlocked from the other side.

    Map of Concrete World B

    In Concrete World B (灰色の荒野, Haiiro no Kouya, Gray Wilderness), there are five floating diamonds: one white, one blue, one yellow, and two reds. Using the Fairy effect will make them spin. After using the Fairy effect just once, a diamond will activate and flash colors, even on subsequent visits. It will move slowly in random directions as you chase it down, and interacting with it will return you to the main area, south of the elevator doorway.

    Southeast of the entrance from Concrete World A is a green button, which will take you to the Animated Hub. Northeast of it is a gray bench.

    If the connection from Urotsuki's Dream Apartments to Legacy Nexus is active:

    Concrete World B

    (Note: The Fairy effect must be used only once to unlock access to Concrete World A.)


    • Concrete World was originally the main place where you could find Smile-san and the Spacesuit effect in previous versions of the game. Now this (and all its other previous features) have been moved to Flying Fish World. You can still travel up the elevators, but doorways that lead to particular places no longer work.
    • It's important to note that BGM 055 can only be fully unlocked if you enter the elevator portions of Concrete World A.
    • The map containing the elevator portion of Concrete World A is one of two largest single maps in the entire game, tied with the Underground Laboratory.
    • Concrete World B had, in the older versions of Yume 2kki, a direct, one-way entrance directly from the Nexus.
    • In older versions, it had a brighter color scheme.
    • The music for Concrete World B is sampled from a sample disc named Pandora's Toolbox called "The Bosun Freaked".
