Part climber, part playhouse; the Simplay3 Young Explorers Discovery Playhouse provides hours of climbing, crawling, cooking, creative and cooperative fun to your family's playtime, and can be used indoors or out! The playhouse is part of the customizable, add-on Young Explorers modular play system from Simplay3 and can be expanded with other play sets from the system for even more fun. This toy is easy to move in- and outside because it has been purposefully designed to fit through standard doorways.
