The Wii version of this game only allows multiplayer in Toy Box mode. In the Play Set area where you complete adventures the Wii version only support single player. According to the Disney customer help website the PS3, Xbox, and Wii U versions support drop-in, multiplayer in both Toy Box and Play Set. The kids are pretty disappointed. Also, creating your own Toy Box is extremely complicated. Don't waste your money on this product. I would return it if I could.
