Tilde is a boy with wings. The hurricane brought Tilda to Galichya Mountain in Lesnoe Urochishche. He decided to live in the forest and made friends with forest inhabitants - the beaver Beaver, the squirrel Naushka, the chipmunk Bronya, the woodpecker Nok and others. They built a house for Tilda on oak branches. The bloodthirsty wolverine Maha came to the forest. She attacked small and weak ones, stole bird eggs and ate chicks. Tild came up with a trap to catch the wolverine. The friends dug a hole under the tree, attached a sliding loop of spider web rope to the end of an elastic branch, and installed it at the bottom of the hole. Makha was lured into a trap, she was caught, repented and was released.
