You were really hungry so once you started eating the oats, you craved for more and more. They tasted extremely good and plus, your stomach was already empty which only made them even tastier. You kept eating and eating, the more you eat the better they became and despite your mind telling you that this is a horrible idea and that you could become a donkey again, you didn't listen nor care about it and just continue eating. Unbeknownst to you, while you were eating the oats, all of the changes started coming back and coming back and they were happening even quicker. The ears, the tails, the hooves, muzzle; they all came back. Heck, you were already on all fours when you started eating so these changes only made you look more animal than you already are. Despite the changes happening, you didn't notice nor care care about them; sure, you felt strange in a few parts of your body but to you, they weren't important and only seemed like barriers trying to stop you from enjoying your meal, which by now was the only thing you cared about.

By the time you had finished eating, you had already became full donkey and you didn't realize it until you looked at yourself in a puddle nearby. When you did though, you were calm and actually a bit happy. You felt satisfied when you see that donkey muzzle, it felt more natural than your face had ever were as a human. You embraced your donkey self and even wondered how much worse your life had been if you were a human. To you, human life now seems alien and weird. Now as a donkey, you wouldn't have understand those drawings they made (aka letters) or have to go to places called "schools", you could sit around all day and do nothing but eat. To you, donkey life was more simple and better suited to you. After all that, you decided to celebrate your new donkey life by treating yourself to some oats but before you did, you heard a noise at the door and it was...
