Once upon a time, there was a grumpy cat named Tom. Tom liked to sit by himself and watch the birds. One day, he saw a big knot in a tree. Tom was very curious about the knot.
Tom's friend, a happy dog named Max, came over. Max mentioned the knot in the tree too. Tom and Max wanted to see what was inside the knot. They climbed the tree together.
When they reached the knot, they found a little bird inside. They thought the bird would be scared, but the bird was happy to see them. The bird said, "Thank you for visiting me!" Tom and Max were surprised. They became friends with the bird and played together all day. Tom was not grumpy anymore.
