Leon lived in a small house at the end of the street. He liked to spend most of his time in the attic, where it smelled of dust and old books. One cloudy afternoon he played there with his cat Migotka. Twinkle loved to climb cardboard boxes and Leon dreamed of adventure. Suddenly, Migotka jumped onto a huge oak box and meowed loudly. Curious, Leon opened the lid. Inside lay all sorts of treasures: letters, old glasses and.... his grandfather's gold watch! The watch was heavy, had a convex glass and strange buttons on the sides. Leon pressed one of the buttons. Suddenly the watch shuddered and coloured lights flashed across the room! The flicker wagged its tail and snuggled up to Leon. The watch ticked quietly, and then.... the whole attic began to change. The walls disappeared and were replaced by tall trees and large ferns. Leon blinked his eyes. Where had the attic gone? There were giant dinosaurs standing around him and Migotka! One of them looked straight at Leon and its tail rustled in the bushes. Leon took Migotta in his arms and took a step back, but then the watch shone again. Would they make it home? What will happen if they press another button?
