The Bat
Once upon a time, the animals living on the ground and those flying in the sky fought against each other. However, a bat could not take part on either side because he was timid and had no courage. When the beasts seemed like winning, the bat went to them and said, "I would like to fight with you." They believed him. Yet, the bat began to worry, as the birds started to move ahead. So, the bat went to them and begged, "I am on your side because I am winged, too." They pleasantly accepted the bat. "Sure. Since you have wings, you are on our side."
