The story will never truly be finished because I'll keep adding monsters to it, but I keep the 'complete' tag for peace of mind.
Twilight, after pleading by Cheerilee, goes to the school of Applebloom, Scootaloo, and Sweetie Belle in order to teach the children there about what creatures they should never face. Regardless of how she explains it, the children almost have a heart attack.

Later down the line, she discovers an old booklet by a hunter named 'Spiral Tooth' and goes through their rather 'colorful' descriptions of the monsters they've encountered with Spike.

This is basically just a bestiary of things that pass through my head that I might use in a book or for a story here at a later date.
