Once upon a time, in a small house, there lived a cat named Tom and a dog named Max. They were best friends. Every day, they would wake up early and play together in the yard.
One day, Tom and Max found a big, wet ball in the yard. They were very excited. "Let's play with the wet ball!" said Tom. "Yes, let's play for a minute!" agreed Max. So, they started to play with the wet ball, rolling it around and having lots of fun.
Suddenly, the wet ball began to grow bigger and bigger. Tom and Max were surprised. "What is happening?" asked Tom. "I don't know," said Max. They kept playing with the ball, but it kept growing.
The ball became so big that it filled the whole yard. Tom and Max couldn't play anymore. They tried to push the ball away, but it was too heavy. They were very sad. The big, wet ball had taken over their yard, and they couldn't play together anymore. And that was the bad end for Tom and Max's fun day.
