A very well endowed man. The biggest fish out of the sea men and the Shamu of the ocean. None bigger, faster, or stronger. Yet though he is dangerous and can break you in a second he is looked upon as the loving gentle giant. One who wins not only the hearts of the young but also the old and wise.

If you ever bump into him you wont be sorry.
