The book is full of descriptions of monsters! Sea serpents, slimes, walking mushrooms... it seems to be a guidebook for cooking and eating them. There are many notes on the bookmarks and in the margins, making corrections and posing theories.

At the back is a loose page. The monster on it seems to have been drawn by a child, albeit one who's pretty good at drawing monsters. It has one head fewer than the huge monster Al recently walked inside, but... it does seem similar.

As he touches that page, a memory washes over him.
