In the heart of the Green Forest, right next to the Silver Pond, lived the little squirrel Tosia. Tosia was very curious about the world and invented new games every day. Her best friend was Frankie the hedgehog, who always had a colourful handkerchief with him and a thousand ideas for puzzles. One morning Tosia and Franek were playing hide and seek by the pond. Suddenly Tosia stopped and called out: - Frank, come quickly! Look at the strange footprints in the mud! They both bent down and looked at the paw prints that led straight into the glistening water. The footprints were bigger than a frog's paw prints, but smaller than a beaver's. Tosia blinked her eyes. - Who could have been here? - She asked in a whisper. Franek ruffled his handkerchief and said: - Maybe it's someone we've never met before? Or... maybe a mysterious visitor has come to our forest! Tosia and Franek decided to follow the footsteps step by step. Every rustle, every twig crackle made their hearts beat faster. The footsteps led through the bushes, under an overhanging branch, until suddenly.... there was a quiet splash from the other side of the pond and they saw something that Here the story stops. I wonder what Tosia and Franek saw at Silver Pond?
