MLP infection (ANTHLOGO)

There was a breakout on a disease called Anthlogo. It's unknown on how to get it, but it's seemingly airborne and spread by saliva or contaminated food. Stage 1: cannot be transmitted by saliva yet. Body becomes slightly disfigured, front hooves start to grow talons and eye bags form under eyes. Body gets more slim. Stage 2: head/skull becomes dragon-like, front hooves have talons and are no longer considered as hooves. Back legs are similar to front legs. Can be transmitted through saliva and blood at this stage. Spikes form and tail elongates to a thin, whip-like tail. If pony has wings they get bigger. Stage 3: Final stage. Pony is very aggressive and body is slim and very draconic. Tongue is long and infected might have difficulties keeping it in the mouth. Completely carnivorous and cannibalistic. Horns form and teeth are unnervingly sharp. Apple jack: what in tarnation is this infection doing to every pony?! Twi, where even is this Infections origins. Fluttershy is infected and roaming around killing everything in sight.

Twilight: I'm not so sure.. theres no books on this infection..

Rainbow Dash: oh boo hoo! It's a bunch of bullshit. It's All a hoax!

Rarity: you can't just say that! Didn't you see what it did to Fluttershy?!
