Imagine… a mystical forest hideout where strange and brave forest dwellers defend themselves against invaders intent on their destruction. Now the Imaginext™ Lost Fortress™ brings the adventure to life—with a system of building panels kids can snap together almost any way imaginable. So they can create a whole new adventure every time they play! The hidden arrow launchers really fire and tree branches really collapse when hit! Includes 2 mystical forest characters, the Chieftain and the Centaur.
