Dive into a sea of adventure with Willow the ECR4Kids Climb-N-Crawl Whale. The innovative climbing toy for toddlers and young children is designed to encourage physical activity, imaginative play, and cognitive development. This set includes a whimsical head with tongue and spout, tail, and brightly colored sections that create a crawl-through tunnel with peek-a boo windows. Ideal for use in a playroom with a soft surface or backyard, the play structure provides hours of entertainment. Children can advance their motor skills by crawling forwards, backwards, or climbing on top. School-aged children enhance memory by turning the tunnel into an education game of recalling letters, shapes, and numbers. Beyond physical development, nurture social interaction, when used with multiple kids as they learn to take turns and collaborate. The indoor-outdoor play structure can be configured in various ways, providing a dynamic and flexible learning environment. Combine additional segments for a larger play space, extension pieces sold separately. Parents and educators can disassemble for space-saving storage. For safety and security when using outdoors, the structure incorporates anchor points, anchors sold separately. This product has been designed and manufactured to achieve ASTM F1148 standard for backyard play.
