At first glance, Riley is a girl like many others but, as a matter of fact, she hides a secret (or at least she tries to). All of a sudden - usually in the least appropriate moments - without any warning, she has some small “growth spurts”. She never grows more than a few inches and she gets back to normal within hours. Her record is half a foot and she set it while she was training at the gym… well, her record up to today.
