Once upon a time, there was a Lion in a forest. Once the Lion was sleeping and suddenly a mouse comes and the lion's sleep get's disturbed. The lion gets angry and catches the mouse to kill him. The mouse apologizes to the lion and prays for mercy. The lion shows mercy on the mouse and allows him to go. After some days, the lion was sleeping and some trappers throws a net to trap the Lion. The lion roars loudly. The mouse hears the roar sound and comes to check and sees that the lion is trapped. The mouse thinks of helping the lion. The mouse goes near the lion and starts biting the net. The mouse keeps on biting the net until the net is torn apart and helps the lion to come out of the net. The lion then thanked the mouse.
