Toys play an important role in kids cognitive and physical development. Before starting the formal education with alphabets and numbers, the kids learn and understand different phenomena around them by experiencing things through their senses. They learn about different natural objects, creatures and phenomena by touching them or perceiving them through their other senses i.e. through seeing, smelling, hearing or tasting. In this cognitive journey of learning new things, the toys play a vital role. They try to imitate the real creatures and provide the related information in an effective way much before they actually come across those entities. Designing such toys in itself is an insightful experience. The paper discusses the process of developing one such toy i.e. Crocodile toy. And details the process of how different features of the real creature have been integrated to deliver important information about it in an interactive way. The paper concludes with discussion on tentative strategies to evaluate the efficacy of the toy. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
