One day, a boy named Tim wanted to catch a big fish. He took his fancy net and went to the river. Tim saw a fish jump out of the water. He tried to catch it, but the fish was too fast.
Then, Tim saw a big cooler near the river. He thought, "I can use this cooler to keep my fish cool after I catch it!" He opened the cooler and saw something strange. There was a little green frog inside!
"Hello, Tim!" said the frog. "I can help you catch a fish if you let me go." Tim was surprised but agreed. The frog jumped into the water and caught a big fish for Tim. They both became friends and had a fun day at the river.
