A train, a stacking toy, and a learning system, this toy comes with five cars and an engine that displays different numbers of objects, which match to the number on the car, further reinforcing the number/object correlation. However, the magic really begins when toddlers can attach each of the cars in any order and get a different response. With three modes of play, toddlers are introduced to numbers, colors, animal names, animal sounds, music and other fun sounds. For example, in counting mode, attach the number two car and hear, "Two bells! Ding! Ding! Tickets please!" In colors mode, attach the number three car and hear, "Yellow car! Ready to go! Toot! Toot!" In music mode, attach any of the cars to add a different verse to the train song. Toddlers can press down on conductor Leap to hear three different songs based on the learning mode they have selected. Then for quiet play, toddlers can stack each of the cars from largest to smallest to help build their hand-eye coordination. Requires 3 "AA" batteries (included). Measures 30" x 8" x 15.5".
