One day, Celestia summons the Mane 6 to talk about their hyperactive friend, Pinkie Pie.
She tells them of her past, her real parents and what she can do.
Every day, she tells them of something new Pinkie can do. But the Mane 6 doubt this. She's just Pinkie, right? And then one day, The Diamond Dogs attack Rarity
(reads description) Well, besides the usual Earth Pony powers... well, i'll quote from the story Blue Angel, by V=Pony on why Pinkie might be the most dangerous of the Mane 6. get yourself a drink because this might take a while.
