"Hi! My name is Alex Pianola. Until just recently, I was a pretty normal kid. I used to go to school, lose my homework and munch my way through lots of pizza. But then everything changed the day I met Mr. Flat. Who is Mr. Flat? He's a monster. And since he's been living in my bedroom, the world is not only way more fun, it's a better place to be. Well, it might be a better world, but there are still plenty of problems to solve."--Back cover.
