Once upon a time, there was a little frog named Tim. Tim loved to hop all day long. One day, while he was hopping, he found a letter on the ground. The letter was cold and wet from the rain.
Tim picked up the letter and started to hop back to his home. On his way, he met his friend, the rabbit. The rabbit was also cold and wet from the rain. Tim told the rabbit about the letter he found.
Together, Tim and the rabbit went to Tim's home. They warmed up the cold letter near the fire. Then, they opened the letter and read it. It was an invitation to a big party! Tim and the rabbit were so happy. They hopped all the way to the party and had lots of fun.
