Once upon a time, there was a frog who lived in a pond. He was friends with a dog who lived nearby. One day, the devil appeared and told the frog and the dog that he would grant them each one wish.
The frog wished to be able to fly, and in an instant, he sprouted wings and soared into the sky. The dog wished for a never-ending supply of bones, and suddenly a pile of bones appeared before him.
However, the devil was not satisfied with granting their wishes. He wanted to cause mischief, so he made the frog fall from the sky and the dog choke on the bones. The frog and the dog realized they had been tricked by the devil and vowed to never trust him again.
