  • Flexible Fun. great value.
Our 3 and 5-year-old boys love this toy especially the ability to mix & match the pieces. They know all the names of all the dinosaurs so they love figuring out what the name of their new creation is, for example, "Look at my Bronto tyrano pus!" They love using the tool and are building dexterity. Great toy that we highly recommend ... show more

  • Fun for Christmas
Amazing! This was a Santa gift for a 3-year-old and she loved it! We have been playing nonstop and making the path harder each time. The quality is excellent and the decorations make it more interesting and versatile. Would definitely recommend.

  • Really neat toy
The media could not be loaded. Ok this track is super cool. It’s pretty easy to put together looking at the pictures provided. I got this for my 2.5 year old and he’s obsessed with learning how to use the levers. The pieces are high quality and easy to customize. I am enjoying playing it too! This would be an impressive gift. ... show more

  • Great toy for multiple ages
Bought this for a 3 year old. She and her siblings, 8 and 10, had a great time putting it together and running the marbles. Can be configured multiple ways encouraging creativity. The only reason for not giving it 5 stars is some of the animals are cardboard - wish they were all plastic.
