One sunny afternoon Basia was playing in the garden with her fluffy cat Leo. Suddenly Leo started meowing and digging in the ground under the big oak tree. Basia crouched down and noticed something amazing: a small silver key shining like a star. As soon as Basia took the key in her hand, she heard a quiet hum, as if someone was whispering in her ear: "This key opens the gate to the Land of Clouds".

Basia and Leo quickly climbed them up to a fluffy white gate. Blue clouds floated around, and cheerful music could be heard from afar. Basia lifted the silver key to open the gate....
