Like the title says. Though to be honest, you probably shouldn't read this. It's not very good story, I'm certain there's something else you'd much rather be reading.
Still here? Fine, but don't say I didn't warn you.
So, a new species has been discovered in Equestria, unfortunetly they just want to butcher everypony in sight. Can the ponies survive this encounter? I dunno.

Note:
This is just me having fun. Don't take anything in this seriously.
