Reviews Description: Build a world of castle adventure! Easy-click bricks, sticks and panels make it easy to build and rebuild the Wizard's Castle so many ways, with double-sided snap-in picture panels that let kids choose and change their castle adventures. Inside the castle a spinning floor reveals a secret passage. "Disappear" inside the drop-down tower, or trap an invader at the bottom! 150 piece set includes two play figures that snap on to the bricks, plus a "flying" dragon with wings that flap up and down. All pieces in the TRIOTM Building System work together. Collect them all and build a world of fun!
