Once upon a time, there was a clever little bird. He loved to sing all day long, but he always had to look for food. One day, he found a strange looking spot on the ground. It was a pool of fuel. 
The clever little bird had an idea! He decided to use the fuel to fly away! He put a twig in the fuel, and sang a song as loud as he could. All at once, the twig burst into flames! 
He was so excited! But even though he was now able to fly through the sky, he still had to make sure he always had enough fuel to fly back down! The clever little bird had thought of everything!
