Hello, I’m Agus Pianola! If you have read Mr Flat is here!, then we already know each other, and if you don’t, then let me warn you: my bedroom is full of monsters. Where did they come from? From the Book of monsters, where they lived until the evil Dr Brot released them. Now they’re here, but the worst of it is that Dr Brot and his assistant Nap are here as well, and they’re already trying to sink the restaurant Nautilus. Fortunately Chef Roll, the monster of the kitchen, will help us to come up with a plan to make Dr Brot fail. Adventure and trouble guaranteed!
