What Does My Little Pony Mean by Turning Ponies into Dolls?

When turning black "Why turn ponies into dolls?!" "I am helping them, turning them into dolls at their happiest and happiest moments, and freezing their happiness at this moment forever. They should be grateful to the great Jinghui Cancan! Come on Twilight Sparkle, become dolls with your friends, and I'll make you my exclusive collection! " …………… A bunch of villains "Hey! Why am I being turned into a doll if I don't feel happy and happy?!" "What about joy and happiness? I can change if I want to. Those are only restrictions after becoming black."
