Set Mr Caterpillar’s cogs in motion with this quirky moving toy from Melissa & Doug. Rainbow Caterpillar has six interchangeable sturdy plastic gears on a wooden base. Turn each coloured interlocking gear and it sets the next one in motion, giving the appearance of a crawling caterpillar. The chunky gears can be pulled off and swapped over to teach colour recognition. Toddlers will be fascinated by the colours and movement of this charming toy which helps to develop coordination, fine motor skills and encourages imaginative play. Rainbow Caterpillar also has a series of associated extension activities so you can get even more value out of this classic toy. Gear dimensions: 6cm x 6cm. Age guide: from 18 months.
