Jamie and Tom are ready for another adventure in their secret dinosaur world - and this time they're going right back to the dawn of the dinosaurs and into the Triassic era. There are many weird and wonderful creatures here and the boys enjoy exploring this new place, but when a Lystrosaurus grabs Jamie's backpack and disappears down a hole with it, the boys and Wanna have a problem. If they don't find the backpack, they'll never be able to get home again . . .Join Jamie, Tom and Wanna in this latest exciting instalment of the fantastic Dinosaur Cove series.
I really liked this because it is about dinosaurs, which are my favourite animals besides dragons. The tunnelling trickster was a lystrosaurus and it has powerful claws that can dig a tunnel. The tunnelling trickster took Jamie's rucksack to use it as a bed! Ha ha ha! The tunnelling trickster also ate sume of the pickle sandwiches. Funny! Do you think pickle sandwiches would taste nice? I wouldn't think that would be nice!
Jamie and Tom use an ammonite to get to different places, but first they have to go in the sandbox and dig up the ammonites and they have to look for the right one for where they want to go by looking at the big glass case that has got ammonites in it that are labelled. There are: Permian, Triassic, Jurassic and Cretaceous.
At dinosaur world, the boys meet a strange dinosaur that steals Jamie's backpack, and the backpack has the ammonite they need to get home! If the two boys don't get the ammonite back they will have to stay in dinosaur world forever! That would be horrible. I would never want anything like that to happen with me.
