My grandson has been into dinosaurs since he was about 1 1/2; I think his first words were the names of the dinosaurs, especially from the Jurassic Period. He has every kind and size of dinosaur on the market, so when (for his fifth birthday) he told me he wanted a set for him to play with at my house I was really at a loss at what kind of set to get for him until I saw this one on-line. He loves it! The dinosaurs are perfectly sized to hold and move around the play mat; they can hide behind trees and rocks; and the tub is most convenient for storage, and the right size for AJ to carry it to where he wants to play with it in my home. You can't go wrong with this set of dinosaurs!
