This is a really awesome toy for babies and toddlers.
Balls roll down the tracks and spin as they go. When they hit the bell, it dings and then they clicketty clack along the vertical slats at the bottom too. It seems simple to adults but it's endless fun and fascination for little ones.
This toy encourages problem-solving and curiosity as well as understanding cause and effect. Little ones just love exploring what they can do with it and finding ways to play it in different ways.
