Harry Potter? No, silly, she's HARRY ROTTER. Harry Rotter - her real name is Harriet but she prefers to be called Harry - has lost her Magical Marbles. Harry enlists the help of her cousin, Box Privet, to help her retrieve them. At her behest, Box, who is a wizard with all things electronic, melding electronics and magic, makes Harry an electro-magical wand. Pandemonium ensues.
