You may have read something like this before in a real book. But this is completely different. Why? Because Pinkie Pie is involved.
When Twilight discovers a mysterious stallion alter time and space, even something Celestia would struggle with, she and Pinkie are sucked into a void of pure randomness. There's a place with wall portals, a place with electric mice, and there's a place where everything's pink and girly. Even Twilight can't wrap her head around most of this. Will Twilight be able to find the stallion's motives, or will they remain shrouded in darkness?
I don't know. I'm just the narrator.
