MLP - Organ Theft?

Some weird idea I got while shambling about on entirely too little sleep. Don't think about it too much, I doubt it makes any more sense to you than it does to me.

TRANSCRIPT:

PINKIE: ...Oh, hey, Twilight! Whatcha doin' in my bathtub?

TWILIGHT: Oh, just serial bathing. But that's not important. Come with me, Pinkie... I want to set up a party.

PINKIE: A party? Okay, um, Where?

TWILIGHT:In the library basement...

PINKIE: Whoa! You have a secret laboratory in your basement?

TWILIGHT: Of course, why wouldn't I?

PINKIE: But what sort of party would you have down here?

TWILIGHT: A science party, of course.

PINKIE: Oooh... Wait a minute! This isn't one of those deals where I'm gonna wake up in a bathtub full of ice, with Gummy holding a note saying somepony cut out my gizzard, is it?

TWILIGHT: Pinkie, you don't have a gizzard.

PINKIE:What!? You took it already?  ...Oooh, you're good.
