Smart Max my first animal train is designed for kids ages 18 months - 5 years, offering an early, safe, and fun introduction to magnetic discovery. Easily build the animal train and play with the animals and the conductor. Drive around with the animals in the train or play with each separately. The oversize parts of the train and the animals simply click on the bars, making them ideal for little hands. Smart Max my first animal train includes 25 pieces and is compatible with all other Smart Max sets.
