The mysteries of the forest are revealed by the specially created character Stepan Ugroff. Stepan is a young scientist, a fourth-generation forester and a national park ranger. We used the figure of a mentor, an older brother. Stepan knows a lot about the forest and can tell the children about it in a simple and understandable way. Through such a character, we take away the edification and turn the lecture into a fascinating journey.
The Hedgehog is Stepan's friend, an auxiliary character. He is used for interactivity and helps children find clues. On the billboards with a picture of the Hedgehog, there are hidden letters that finally form the word ECOSYSTEM.
