Once upon a time, there was a friendly fox who lived in a big forest. One day, while the fox was walking around, he met a curious squirrel. The squirrel said, 'Hello, Mr. Fox! Would you like to play hide and seek with me?' The fox happily agreed, and they started playing.

During the game, the squirrel found a secret treasure hidden under a tree. He whispered to the fox, 'Look what I found! But, it's a secret. Promise you won't tell anyone.' The fox smiled and promised to keep it a secret.

The next day, the fox met his friend, the owl. He remembered the secret treasure and couldn't help but tell the owl all about it. The owl was very interested and wanted to see the treasure. So, he followed the fox back to where the squirrel hid it.

When they reached the hiding spot, to their surprise, the treasure was gone. The squirrel saw them and asked, 'Did you tell anyone about the treasure?' The fox hesitated for a moment and then admitted, 'Yes, I told the owl. I'm sorry, Mr. Squirrel.'

The squirrel looked sad but forgave the fox for breaking his promise. They decided to search for the treasure together. After exploring the forest for a while, they found the treasure hidden under a pile of leaves. They were both very happy and promised to keep the secret just between them.
