Once Mara had laid a trap to catch rabbits in the forest. He was worried that somebody else may get there before him in the morning and take away his catch. So, he went into the forest before daybreak. The trap was empty. No rabbit had walked into it. Since there was a stream flowing nearby Mara decided to brush his teeth and wash his face before trekking back home. He broke a small stick from a nearby plant and brushed it third or fourth time. He felt a sour taste in the mouth. He took some water from the stream and put it into his mouth to churn and spat it out. To his surprise, all the teeth which had been touched by that stick had fallen off. Thus Mara had lost his teeth on the right side.
