Llega El Sr. Flat!

Hi I'm Agus Pianola. You don't know it, but sooner or later we are going to be friends. Not long ago I was a pretty normal kid; I went to school, I lost my homework, I made custom pizzas. But everything changed the day I met Mr. Flat. Ah, of course, you don't know who Mr. Flat is yet. All I'll tell you is that he's a monster, and ever since he set up shop in my room, the world is not only more fun, but also a better place. Better but with a ton of mess
