Get the racing aumug. 
Basically MLP fans or just people who really like making unsettling things made this. I think the first one was the smile disease? Idk look it up. Basically you create an AU of MLP where some stupid pony makes an infection/disease/corruption. You show slideshows of the ponies (mostly the main cast) stats and what they have on. Could be rarity is going insane, she looks dirty, but she’s healthy. It shows stages, stage one of infection stage 2 stage 3 on and on until the pony isn’t itself anymore. People also add in other peoples fanmade ponies and it’s rlly cool. If you’re ever interested in watching them find it on yt and start on people reviewing an already made infection. If you wanna make them just do the most terrifying gory things you can think of. So yeah, moral of the story just an MLP AU that involves a super crazy and high detail infection/disease/corruption that someone who probably likes Creepypasta made. Hope this helps :3
Person 1– “Yo did you you do the math for today?”
