One rainy morning, Hania was sitting on the carpet in her room. She was looking for a second sock in her colourful box. Suddenly, she pulled out a very strange sock from it - it was all starbursts and glowed slightly! Hania put it on her left foot, and then.... she felt something happen. The room suddenly swirled and she began to fly as if she were a feather! When she opened her eyes, she saw a wonderland full of rainbow trees and singing butterflies. Right next to her stood a small, purple rabbit with round glasses. - Hello, Hania! - said the rabbit. - I've been waiting for you. We need your help because the Sugar Key has gone missing! Without it, we can't open the secret gate. Hania felt a thrill of excitement. Will she and the rabbit find the Sugar Key? Or would they go through the gate to an even more unusual place? The adventure was just beginning...
