It was from Kingsley Amis’ Colonel Sun, they loosely used it in Spectre.

Nice description!

“A pony lives inside her head. That’s where the seat of her soul is. And this is true objectively as well as subjectively. I was present once - I wasn’t directly concerned - when a stallion in Cowrea was deprived of his eyes. And the most astonishing thing happened. He wasn’t there anymore. He’d gone, though he was still alive. There was nopony inside his skull. Most odd, I promise you.
 
So, Pinkie, I am going to where you are, the inside of your head.”

I made something like that on Minecraft for the X-Box 360

Love it. Pinkie would be an interesting choice for a trip into her weird mind, most definitely Pinkamena.

How about Inside Out, but every one of them is Pinkie. Except for one Pinkamena

I imagine Pinkie Pie having a collection of Animaniacs Episodes in her head.

Dude! This could be considered canon!

I don’t why, but I find stuff like this really cool. <3
