Imagine if you woke up on Fluttershy's couch. You don't scream, but you look at yourself to see if you're still human. You're not, but you're not a pony. You're a draconequus. NOW you scream.
You hear someone else scream, the same has happened to them, except they're a pegasus.....

Brace yourself......... AHHHHHHHHH!!!!!!!
