One day, a little girl named Lily went for a walk. She saw a big rainbow in the sky. The colors were so pretty. Lily wanted to sit and look at the rainbow all day.
As Lily sat, she saw a little green frog. The frog said, "Hi! I am a sour frog. I can make things sour for you." Lily was surprised. She asked the frog, "Can you make the rainbow sour?"
The frog jumped up and touched the rainbow with its little green foot. Suddenly, the rainbow turned into a big sour candy! Lily and the frog laughed and shared the sour rainbow candy. They became good friends and had a fun day together.
