Between classes,Twilight managed to pull Trixie aside for a moment, telling her that she had something really cool to show her.
Once she was alone with Trixie, she put her plan into action. She quickly cast a spell, completely paralyzing Trixie, and rendering her totally mute. Now, she could take care of the next part of her plan without much fuss.
She reached into her backpack and pulled out a pink bunny outfit (made with some help from Rarity), a large rattle, and a diaper. Twilight quickly undressed Trixie, glancing over her shoulders occasionally so as not to be seen, wrapped her waist in the diaper, and then put her in the bunny suit.
As it was, Trixie would already be pretty embarrassed with her situation if anyone saw her, but Twilight wasn’t quite done yet. She cast one more spell on Trixie, causing her angry and embarrassed expression to fade away into a huge, blank smile. Suddenly, Trixie didn’t seem to mind what was happening to her anymore. This was mostly due to the fact that the spell had hypnotized Trixie so that she no longer thought she was a high school student suddenly being forced into a humiliating costume, but rather a diaper-clad bunny hero, destined to save the magical realm of Toyland.
Her work done, Twilight released Trixie and sent her on her way.
What the other students would see later that day would be Trixie, stumbling around the hallway, wearing a diaper, dressed in a bunny outfit, and waving around a rattle; but as far as Trixie could tell, she was on a fantastic quest to save Toyland.”
A little idea that came to mind while watching the Game Grumps play “Myth Makers: Trixie in Toyland.”
