One day, when Sid is walking to school, he suddenly gets a happy feeling. In fact, he feels so happy that his paws lift off the ground, and he floats right up to the sky! He can’t wait to tell his friends at school, but of course they don’t believe him. "Don’t be daft," scoffs Ben. "You’re a dog, and dogs don’t fly." Even Sid’s teacher shakes her head at him. Now Sid is one unhappy little pup. Can anything ever get him flying high again?
