Once upon a time, in a big, green jungle, there lived a lion and a little mouse.
One sunny day, the lion was sleeping when the mouse accidentally woke him up.
The lion was angry and decided to eat the mouse, but the mouse begged for mercy.
The mouse promised to help the lion one day if he let him go. The lion laughed at the idea.
Months passed, and one day, hunters trapped the lion in a net and he roared for help.
The mouse remembered the promise and started nibbling on the net until the lion was finally free.
From that day on, the lion and the mouse became best friends and helped each other in times of need.
