Pop Up Dinosaurs by Tolo

This pop-up box helps children discover the dinosaurs in the eggs by having them push, slide, and rotate large buttons that are easy to grasp. It's a nice basic cause-effect toy with a few drawbacks. Strengths: This toy doesn't light up, play music, make sounds, or move around. It's just a basic pop-up box that helps children learn simple cause-effect relationships. Weaknesses: The buttons can be difficult to operate if children have any strength issues with their hands. The dinosaurs are sometimes difficult to push back down into the eggs and the eggs don't always latch properly. Price: $19-$23. Where to Buy: I don't believe that this toy is available in mass markets and longer, but it can be found on amazon (http://www.amazon.com/) or through eBay.
