You really enjoyed that. Hoping this wasn't a dream, you pinched yourself. But you didn't wake up. Braying happily and rubbing your fur, you head into the next room. There was another wheel there. You bray excitedly, wondering what it will tell you next.
"Ah, how are you feeling?" The voice asks.
"Hee-haw!" You respond, enjoying how real it feels. That annoying voice in the back of your head appears again. You violently push it away.
"Good. Braying is so much easier for you. But now, it's time to eat." The voice says.
You look around in confusion.
"Human food is not fit for you. You want something healthier, something plentiful. You want hay, and you want to eat it like a donkey. It's much more efficient." The voice says.
Braying agreeably, you lower your head into the troughs under the wheel. Biting up a piece you chew it thoughtfully. It tasted delicious. You gratefully feel your face push down into the hay as you eat. Your lips also grip the hay better. You eat to your heart's content.
"Now, look in the mirror. I bet you will like what you see." The voice tells you.
You look up. Staring back at you is the head of a donkey on your shoulders. You give a happy bray. So that is why it was so easy to eat!
"Move on to the next room for more fun!" The voice says.
