One day, the red panda Flopson woke up and realized that her friend, the striped animal named Tjalle, was missing. Flopson takes a huge risk - she goes in search of a friend, although she has never left her native walls before! Flopson will have to make friends with a hamster and a titmouse, join the police squad and fight back against the evil ferrets... But where is Tjalle? What if you can't find it in the park? What if he became a city animal and doesn't want to be friends anymore?!
