It’s not only important to be able to identify your foes, it’s also crucial that you know their names. Familiarize yourself with them so you may cry them out in times of duress, perhaps so that a passing hunter in nearby woods might hear it. A description would help, as well, but with these pages in question a picture really is worth a thousand words.
I really like that it points out the leech’s ghastliness. Otherwise it would just be your standard stupid leech.
