Hi, I'm Agus, the friend of Lidia and the monsters. You know me, don't you? I've had many adventures with them, especially because Dr. Brot always wants to give us a hard time. And this time he's given us quite a scare: he's lost the Book of Monsters! The monsters have a page, but without the whole book they can't go home, and Lidia and I are ready to do anything to help them!
