Zosia really enjoyed visiting her grandfather Staszek. In her grandfather's garden you could find big curly pumpkins, raspberry bushes full of fragrant fruit and a little crib where Puffy the cat always slept. One warm afternoon, while Zosia was digging holes in the sand, she noticed something shiny under an old raspberry bush. She brought it to her grandfather. It was a small clock with coloured hands and strange buttons all around. - 'You've found an unusual thing,' said grandpa with a broad smile. - This clock can do more than it seems! Zosia was very curious. The watch had a button with a picture of a dinosaur, another with a castle, a third with a rocket and a fourth with a balloon. Puffy the cat started to push the dinosaur button with his paw. - I wonder what will happen if we push it! - giggled Zosia and before grandpa could say anything, she pushed the button. Suddenly she felt a soft breeze blowing around her, heard strange bird noises and.... she saw that her grandfather's garden had turned into a dense, green jungle! A huge green dinosaur stood next to her, looking at her curiously. The puffin hid behind her leg, but immediately stuck its head out and purred quietly. Zosia wanted to ask the dinosaur its name, but she heard a powerful sound behind her: something big started approaching through the ferns. Zosia and Puff squeezed each other's hands and tails, and the shadow moved faster and faster towards them....
