The Mantiwhore

Nightmare Moon sailed through air in her blue smoke form and weaved her way through the trees of the Everfree forest, her efforts to scare off the ponies that represented the elements of harmony had failed and she realized that perhaps a real threat would be more effective, so imagine her good fortune when she came across a manticore. This large beast was famous for eating ponies if the mood so took it, now all she had to do was irritate the poor creature in some fashion, induce some kind of pain that would make it angry and lash out. Nightmare Moon considered her options, a thorn in the paw? No, that kind of thing is so easily removed that the manticore itself could deal with that, tie its tail to a tree? No, whatever material she used the manticore could easily break.

Nightmare Moon needed something simple, something that wouldn't be easily fixed by magic, something that the manticore couldn't solve without help and definitely something that even those damn ponies wouldn't be able to do. As she heard them all making their way through the trees she realized she had to think of something and think of it quickly, she didn't have time to fuck around... then it was as she thought that, that she had an epiphany, her idea to enrage the manticore was...... unorthodox, though if it worked, then nothing could stop her.
