The oxen transports you to the top, but you can't leave it there.

A turkey chats with a cow. The turkey says: I hope to fly to the top of the tree, but I don't have the courage. The cow said: Why don't you eat some of my cow dung, they are very nutritious. The turkey ate a little cow dung and found that it did give it enough power to fly to the first branch. The next day, the turkey ate more cow dung and flew to the second branch, two weeks later. The turkey flew proudly to the top of the tree, but soon a farmer saw it and quickly shot it from the tree.
