She's an evil enchantress!
She does evil dances!
And if you look deep into her eyes,
She will put you in trances!
Then what will she do?
She'll mix up an evil brew!
And she'll gobble you up
In a big tasty stew!

But would Pinkie Pie really say something so mean about somepony she's never met?

Turns out, she's got a reason for every line in that song.
