(Thsi version is just the last one except the story doesn't have a clear ending)
The door opens and you see another boy coming in. You tried to warn him but he ignored your brays. He approaches the oats and like you begins to stuff his face with them. Again, you tried to stop him but he pulls you away. "Go away you stupid animal!" the boy shouted "Heeeeeeehaaaaaaaw heeeeeeeee haaaaaaw heeeeeee haaaaaaaaaaaaaw (No please! You have to listen to me! These things are bad, you'll turn into a donkey like me)" you "screamed" but he doesn't listen to you instead he evens pulls you away. You kept insisting but to no avail he pushes you away and continues eating so you stopped and decide to watch him eat and just like you, turn into a jackass. His transformations ensues. First, his ears gets longer and pointier. His tails gets released, fur covers his body, his hands/feet changes into hooves and his face turns into a muzzle. You were terrified as you stand there having to witness someone go through the same process as you did with the same ignorance and obliviousness to what they would become as a consequence of this ignorance while you stood there unable to warn of them of their fate. When he had finished eating, he too had become a donkey but instead of being horrified of his fate, he seemed happy and satisfied with his new form. At first you thought that he had become crazy or he had wanted to become. But then you realized that you were actually spared of the mental changes. Sure, you can't read, write or talk but you can still understand humans and retain human intelligence. After that, the boy comes to you and "says" "Heeeeeeeee haaaaaaaaaaaaw (Why don't you want to be a donkey?)" "Heeee haaaaaaaaaaaw heeeeeeeeeeeee haaaaaaaaaa (I don't wanna be a dumb, useless animal)" you replied "Heeeeeeeeee haaaaaaaw (But it's fun) Heeeeeeeeeeeeeee haaaaaaaaaaaaaaaw (You can just do nothing all day)" he said. "Heeeeeeee haaaaaaw (But it's boring)" He keeps telling you about how great donkey life is but you ignored him. After some time, the door opens and you see.....
