Mini was adopted by the big cats at the zoo. He is tiny - in stark contrast to the rest of his family. But precisely because he is so small, he can slip through fences and visit his relatives. Each family member teaches him what they are particularly good at. The only thing he struggles with is roaring, as his attempts always result in just a scream. However, in a dangerous situation, Mini shows what he has learned: he is brave and strong and can scream so loudly that even the wolf runs away from him.
