Ayda is only five, but she can already do a lot: recite poems, dress herself, speak Persian and German, and ride a bike without training wheels. Nevertheless, Lisa and Paul from kindergarten never take her along when they go out. They call Ayda "Knirps" because she is so small. So one day, Ayda sets out on her own and meets the rabbit and the big bear. The two are afraid of humans because they are not taken seriously or even feared. But they open up to Ayda. Together, the three discover how exciting the world is, and soon they form a deep friendship. They are rarely "üzüntülü" - sad - anymore.
