Fluffy was an ordinary little cat who lived with his grandmother in a colourful house by the woods. Every day, Fluffy played with Fruzia the sparrow and Rudy the squirrel. One morning, when the sun was shining very brightly, Fluffy noticed something in the garden that had never been there before. Behind the strawberry bush appeared a small wooden door with a shiny golden handle. They were so small that only Fluffy could pass through them. - Check it out! - called out to Fruzi and Rudy. - Where did this door come from? The friends came closer. Suddenly the door began to shake slightly and they heard quiet laughter. From behind the door came the smell of raspberries and the sound of quiet bells. - Come on, let's see what's on the other side! - whispered Ruda. Fluffy put his paw on the door handle.... And at that moment the door began to glow with a thousand colours. Everyone held their breath. What would happen when Fluffy opened it?
