Pinkie Pie wants a pineapple.
No ordinary fruit will do, she needs a Sweet Apple Acres pineapple.
Pinkie won't let little things like Applejack's logic "A pineapple ain't an apple!"
or Twilight's loss of sanity "She's right, go to the store!" stand in her way.
What follows is a tale of romance, science, and pinecones.
Also, Twilight summons a demonic entity but that happens every month so isn't important.
