One day, the Kauravas and the Pandavas were playing together on the banks of river Ganga. Now, once again, don't ask me why there because that's the only place. Indians rely a lot on these rivers for their livelihood. Anyways, at that time, Shakuni was poisoning his nephew's mind, trying to tell him to kill his enemies when they were still weak. So, when everyone was playing, Duryodhan took Bheem, the strongest Pandav to a beautiful hut and fed him poisonous food. Our Bheem, the hungriest child ever, ate everything and then he fell unconscious.

Duryodhan tied his body with a stone and threw him in the river Ganga. Bheem sunk to the bottom of the river when a snake bit him and took out all the poison from his body and took him to the king of snakes, yes sorry but I forgot his name.

So, Bheem was soon awake. He was surprised with the aquatic life and the fish and plants around him. There, the king of the snakes was sitting, warning him, "Make sure that you are aware of Duryodhan. He wants to harm you and he had poisoned you. We sucked the poison out of you and from now, you can breath under the water and have the strength of hundred and one elephants. May you always be successful in your endeavours."

With that, Bheem joined his hands, took his blessings and returned to Hastinapur. Of course this story was just a way to tell the readers the personalities of Bheem (his strength) and Duryodhan (his eagerness to win overpowers his sense of dharma and karma). It was not true, I think. I don't know. There are many such stories in the Mahabharat which don't contribute to the flow of the story but help in the character development.

Sorry for being this late but I find this story a little boring. So, I didn't have enough motivation to write this down. That's why the delay.
