The area is designed around Shy Guy's Toy Box from Paper Mario for the Nintendo 64, using creative differences with how it was set up and everything. The Shy Guy Army and the Magikoopa Military wage war within the confines of this miniature battlefield, seemingly unaware of the real world that lies outside of it. Heads of the Shy Guy Army can be found within at special points, but none of the commanding officers from the Magikoopa Military can be seen. There are also special items that you can find within; their use has yet to be put in, and it'll probably take a bit of thinking to figure them out.
The monsters are to be on par with the same monsters in Temple of Chronos/Noin, only it is intended for neutral kills.
