Story topic brainstorm!

So i spent today thinking about all kinds of different ideas for stories, and a few took root in my thoughts. Here, I share them in the hope that they might see the light of day!

- Beware, The Choco-Trice:
Twilight is experimenting on a cockatrice. Cue Pinkie to interrupt a spell with chocolate, and suddenly, we have a choco-trice! instead of stone, it changes you to chocolate! So now we have this badass chicken snake dragon bat thing that can go all majinn buu on these ponies and make them into chocolate! Hilarity ensues, and (Insert mandatory Cupcakes shoutout between Dash and Pinkie when Dash becomes a choco-dash), and Twilight eventually curbs the effects before Pinkie loses control and eats all the chocolate!
Weird idea, sparked by an easter pic someone on dA made. I really wanna see it, but I can't seem to write it just right.

- Comedy writers!! Look no further! Introducing: "The Equestrian Roast of [insert famous pony or royal figure]. Just a mish-mash of raunchy humor and plays on character toward one of Equestria's top celebrities. Say just the things you've always wanted to drunkenly slur at the ponies you love, and get out free!

- Mirror Chase: Twilight casts a spell to see a bunch of her reflections at once in a mirror (idk, something for Rarity maybe) and instead pulls herself into the mirror. She travels from mirror to mirror, much like the pictures at Hogwarts. She can't find a way out, and cant talk to anypony, cause she's just a sheet of glass. she can, however, appear when somepony steps into view, their reflection changing to Twilight. Where has Twilight gone? Why can't Celestia find her student in the magic-stream? And why does Spike's mirror reflect his caretaker instead of his rock(dirt) hard(soft) abs? Will Twilight ever return?

The Great Book Search of Ponyville: Twilight (Damn, she takes blame for a lot, eh?) is organizing her books when, a large crash echoes as the door bursts open to Dash and the rest of the mane six following close behind. The spell backfires (of course), effectively organizing everything except for Twilight in the room as a book. So. Everypony in the room is all suddenly *poof* a book! and all the other books fall to the floor. Now Twilight has to re-organize her library, and separate her friends from the regular books, and reverse the spell before it's too late. Only her knowledge of her friends will help her find them, since the ponies-turned-books are just regular science texts and references. She'll have to read them all and find the subtle clues in the writing to find the right one.
Weird. Idea. Moving on!!

That's all for now. I'll post more when they come to me. if you use one, credit me for the idea please.
