Kids can play and learn with their favorite Sesame Street pals. Big Bird helps teach letters, numbers, colors, shapes, animals and more. Big Bird prompts kids to connect a train car with a specific letter, number, shape or color. When they connect them in the proper sequence, the train starts up, plays a tune and drives around in a circle as the Sesame Street characters bob up and down and talk to one another. Their clever phrases entertain and encourage. Songs include “The Alphabet song” and "I've Been Working on The Railroad,” which play when specific tasks are accomplished. Lights add to the fun. There’s also a special baby mode just for music. Requires 2 "AA" alkaline batteries (included).
