One morning, a mouse went to the little girl who sells brown flowers by the temple and asked for one. 

"Shoo," said the girl and chased the mouse away. The mouse felt very sad and went away. In the evening, the mouse told his friends about his humiliation in the morning. His friends felt sad and together, they hatched a plan.

That night, all the mice rolled into the girl's flower basket so they would appear as a basket full of brown flowers. The girl too fell for it and went to sell them to her customers. The moment the buyers wore the flowers on their plaits, the mice became themselves and gnawed on the hairs of the women, who screamed in fear and demanded that the girl refund their money. 

The poor girl lost all her money and learnt that she shouldn't annoy mice anymore.

The moral of the story is: Nothing. Remember, the only aim is to giggle.
