Once upon a time, there was a big tiger. The tiger was very filthy. He had dirt all over his fur. One day, the tiger was walking in the forest when he met a little bird.
"Hi, tiger!" said the little bird. "You have so much dirt on you! Let me help you get clean."
The tiger agreed, and the little bird started to pick the dirt off the tiger's fur. Soon, the tiger was clean and shiny.
But then, something unexpected happened! The tiger started to change colors. He was not a normal tiger anymore. He was a rainbow tiger! The little bird and the tiger became best friends, and they played together in the forest every day.
