Follow the lights and make the rainbow shine in the 36002 Light Up Rainbow Set. This interactive toy train set introduces toddlers to basic sequencing and cause and effect patterns in a fun and engaging way. The aim of the game is simple - light up the rainbow with all of its beautiful colours. To do so, just follow the blinking lights on the tracks with the little wooden train. Each time you correctly follow the lights through the cloud and complete the challenge, the rainbow will light up one of its four colours and a cute melody will play. Light up all the colours and youll be lucky enough to experience a playful song and light show.
