Once there were two friends(Mouse and Walrus).
They were very good friends. Mouse lives in a wide trunk of a big tree which was situated at the bank of a sea.
And Walrus also lives in that sea. Both friends play various games.
Sometimes mouse climbed on the tummy of Walrus and makes mustache when Walrus got sleep.
They were very happy and enjoying their life.
But one day some human beings cut the tree and mouse got killed by them. Walrus become very sad and left that place. He travels very long distance and without eating any thing.And got very tired and decided to take rest So he stop under the tree(this tree was also on the bank of sea).
Suddenly he found that a mouse was sinking in sea water.Mouse was looking exactly to his friends.
So, Walrus considering the mouse as his friends saved his life. And hence he got a new friend and started living there happy.
