Toy World (aka Lego Blocks World) is one of the main worlds accessible from the Nexus.
Features
The current version of this world is fairly small and is filled with multi-colored Lego blocks. By using the Rainbow effect in the Nexus, you can cause the bricks on the Toy World portal to change color. If you go up the ladder on the blue blocks, you'll come to a pink floored area. When you step on the purple checkered tiles surrounded by purple round blocks, Urotsuki will slide around. You will only be able to control where she goes by using an effect that enables her to float, such as the Spacesuit effect. Go into the doorway in the blue block to go to the Day & Night Towers.
There is an entrance to this world through the Art Gallery, where you can "play" tic-tac-toe with a sane Shadow Lady. Travelling down from this entrance takes you to the giant version of Toy World.
There is a plate of cheese in this world. Eating it will make you shrink, eating what remains on the plate will make you grow back to normal size. This can be beneficial, as some doorways and areas in this world are only accessible if you shrink.
(In the previous versions, there were more cheese around this area, among them was a special one which used to grow you into a giant and transported you to the Mini-Town.)
If you go into the door immediately on the left, you will be transported to the Mini-Maze.
If you go through the door in the set of red Lego Blocks, you will be transported to the Red Brick Maze.
By shrinking, you can go through the door in the red wall, which leads you to another part of the Day & Night Towers.
