All aboard The Critter Express! This motorized musical train is ready to go on tour. Build the railroad by connecting all 8 tracks together, easily link the 4 magnetic cabooses, and then choose the mode that’s right for you! Go for the Motorized Mode to watch the train go round and round on its own, or switch to the Free Wheel Mode to control the journey. You’ll hear the train choo-choo its way through the 36″ railway either way! And if you really want a party, just press the Music button and watch the cat twirl, the dog groove, and the frogs drum! Full of lights and sounds, this toy also improves gross and fine motor skills. 3 AA batteries are required and included. Recommended for children 2 years and over.
