We have been given two of these recently for DS - the original one (where Harry finds the dinosaurs in the attic) and Harry and the Dinosaurs Make a Splash (where they go to the water park).
DS absolutely enjoys them, but I really, really don't. Am I alone in this? I like the fact that it introduces the names of dinosaurs and stretches Ds' ability to pronounce unusual sounds in the names of the dinosaurs, but I am finding the remainder of the language poor and the story quite boring.
