Plastic rocker toys are typically small, durable toys designed for children. They often feature bright colors and playful designs, resembling animals or characters, with a rounded bottom that allows them to rock back and forth without tipping over. These toys are popular for toddlers and young children as they provide entertainment and encourage motor skills development through rocking and balancing. They are usually made from non-toxic plastic for safety and come in various shapes and sizes to appeal to different age groups and interests.
