Turn the gears slowly and watch each interlocking segment move the next, or see how fast your child can make the caterpillar "crawl" on the wooden base. This rainbow-colored gear toy is hands-on fun at any speed! With their bulky, notched shape, the colourful gears are easy for children to fit onto the colour-coordinated pegs . . . then rotate, remove and rearrange. Toddlers will be fascinated by the colours and movement of this charming toy.
