Moving toys have existed for thousands of years, with some of the earliest found dating back to 3000-1500 BC. These early toys were typically made from natural materials like rocks, grass, sticks, or clay and often took the form of animals. Pulling and pushing toys from ancient civilizations were commonly shaped like animals and made from materials like clay, wood, lead, and ivory. In the 19th century, rolling toys helped young children learn how to walk and stand on their own. Common examples of early moving toys included horse rocking toys, yo-yos, and duck-shaped rolling toys with hopping heads.
