One sunny morning at school, Megan and Bella were playing hide-and-seek during recess. While hiding behind a big bookshelf in their classroom, they stumbled upon an old, dusty clock with glowing blue numbers. As soon as they touched it, the clock started to beep and flash! Suddenly, the room began to spin, and the girls felt like they were flying through the air. When everything stopped, they found themselves in a strange, empty room filled with stars twinkling all around them. A small, talking robot popped out from the clock. 'Hello, I'm Zip!' he said. 'Welcome to the Time-Traveling Clock!'
