In a vast and endless forest, there lived a mother squirrel and her children. In order to feed her children, mother squirrel often goes out to find nuts, but enemies are hidden everywhere in the forest, peeping at them from time to time. The mother squirrel could only take the children to hide in the nest. The two little guys could not keep their loneliness, so they pestered their mother to tell them stories. So the mother squirrel told them a story about the grunt cow. A long time ago, there lived a clever little brown mouse in the forest. Once he was walking in the forest, but he was attacked by owls, foxes and poisonous snakes. The little brown mouse is weak and weak, so he made up a story, saying that he is a good friend of the Gruffalo, and he is going to see him now. The grunt cow is tall and strong, and looks particularly scary. His favorite food is foxes, poisonous snakes and owls. Animals such as foxes are originally bullying and fearful. After listening to the big talk of the little brown mouse, they believed it to be true and scared away. The little brown mouse thought that it was safe now, but he didn't expect that the good show was yet to come..
