The SmartLab: The Amazing Squishy T-Rex Toy models the world's favorite and most recognizable dinosaur, inside and out. This anatomically correct model can be examined on the inside by removing the six detachable hide pieces. On the inside are six bone pieces, three muscles and five organs. Children are easily mesmerized by tactile feedback, and the joy of disassembling and reassembling this SmartLab T-Rex Dinosaur Toy will keep them entertained for hours, especially as they play with the squishy bits inside. When they aren't playing with the SmartLab Dinosaur Play Set, a display stand keeps it out of the way. Bright young minds will also love the included book.
