Rip up Dudley's birth certificate
From Create Your Own Story
You grab Dudley's birth certificate and chuckle while you pay back Aunt Petunia. By the time you're done, there are a million and one pieces of paper on the ground.
There is a big bang and you fall to the ground. "BOY, you better let me in or else I'm going to box your ears!" You see the window is open and a bag of chips is on the ground from Dudley's snacking. You've never had chips before and wonder what they taste like.
