When is the appropriate time to discuss topics such as the body and reproductive organs with children? How can we teach them behavior rules regarding human interaction? Are there "good" and "bad" secrets and how can we help children distinguish and manage them? Now educators have the assistant Frixos, a hedgehog. The book is a comprehensive educational intervention for preschool and primary school children, aimed at promoting sexual health and protection against abuse. Through stories, creative experiential exercises, and games, children discuss topics such as the body, public and personal space, family relationships, emotions, and protection against sexual abuse.

The educational program was awarded the Excellence and Innovation Award in Sexual Education in 2019 by the World Association for Sexual Health.
