"Darling, making a sonic boom can cause a whole lot more problems if you don't know what you're doing. Be sure to wait 'til I can give you some lessons."
— Savannah in Tracy's thoughts
Savannah promises Tracy to teach her how to do one of her famous sonic booms, but Tracy is so anticipated that she tries to do it herself. She ends up going too far and crashes, and soon learns that some things need to be learned with the help of an adult.
Moral: You can’t do certain things alone without the help of an adult.
