Johnny is an eight-year-old boy who fantasizes about being like people, animals, or things that he admires. He imagines himself as being many things, such as a famous athlete or a famous scientist or even an awesome sports car. These fantasies come to life for him one day when he discovers a magical cloud that grants him special wishes for a day. His adventures with this magical cloud allow him to experience a day as a parent, as a car, as a magician, as a duck, and as a chipmunk. The journey of having these special wishes granted for a day teaches Johnny how to question and learn, and he discovers he rather be himself.
