Once upon a time, there was a small engine named Casey. Casey was a cheerful little engine, but she was not very powerful. She was often assigned to pull small loads, and she dreamed of one day being able to pull big loads like the other engines.
One day, the train station manager asked Casey to pull a heavy load of supplies to the top of a tall mountain. Casey was nervous, but she was determined to try her best.
As she started up the mountain, the load began to feel heavier and heavier. Casey's wheels spun, and she began to slow down. But she refused to give up. "I think I can, I think I can," she said to herself over and over again.
With each "I think I can," Casey's wheels turned a little faster, and she pulled the load a little farther up the mountain. Soon, she was halfway up the mountain, and she could see the top in sight.
But then, disaster struck. Casey's engine began to overheat, and she ground to a halt. She had come so far, but it seemed like she would never make it to the top.
Just then, a group of animals appeared out of nowhere. A squirrel, a rabbit, and a fox. They saw Casey's predicament and decided to help.
Together, they pushed and pulled Casey up the rest of the mountain, encouraging her with each step. "You can do it, you can do it," they said.
And with their help, Casey finally made it to the top of the mountain, where the supplies were delivered to the grateful townspeople.
From that day forward, Casey was known as "The Little Engine That Could," and she was admired and respected by all the other engines. She had proven that even the smallest and weakest of engines could accomplish great things with perseverance and determination.
