Of Snail Slime/YMMV


 * Big Lipped Alligator Moment: Though there's a good argument for saying the book is made up of them, the Slugs come in right out of nowhere in the middle of a chapter, are quickly killed, and are never mentioned again.
 * Crosses the Line Twice: Sharpened to a refined point.
 * Mary Sue: The two brothers tendency towards fits of "brilliance" and superhuman-feats cause them to come off as this, especially given their status as Author Avatars.
