It's fun and educational! Learn about anatomy with the help of a T-Rex. You can even feed it! After seeing all the Lego dinosaur skeletons I was dissapointed, it's all white and you don't learn anything. I think the final design should be shorter and fatter but this was a complicated enough build. I took a lot of time to fit all the organs and hinges in and still have a sturdy design. Sadly the head doesn't turn, or else you couldn't feed it. Watch out for your fingers when you do!
