I got the chance to do things that I dreamed of when I was a kid: I got to travel around the world; I had my own 'Goosebumps' attraction at Disney World; I've been on TV and had three TV series.

When I was a kid my family was really poor and I remember one Halloween I wanted to dress up really scary and my parents came home with a duck costume. I wore that costume for years! I hated it.

I started writing when I was 9 years old. I was like this weird kid who would just stay in my room, typing little funny magazines and drawing comic strips.

The next day, Greg is so large that he cannot even ride the car to school because he can't fit in the car. His parents believe this to have been caused by a food allergy and resolve to take him to the doctor later.

I've had a very sheltered life. What can happen to you if you stay home writing all day?

I love theme parks but I'm a real chicken on rides. I'd rather invent scary rides for my books than go on them for real.

It's my job, too, to keep up with pop culture and what the kids are into 'cause you don't want to sound like an old man trying to write for kids. I spend a lot of my time spying on them.
