If you have ever been underwater you'd know that the first thing you see are yaks. Nothing prepares you for this before you descend into the liquid ocean. How could one prepare for the amazement felt? The yaks are small, smaller than trees and some types of furniture. The yaks also travel in herds of up to ten billion, they find a hell of a lot of other animals and plants do not attack them when in a herd.
Harvesting yaks is quite difficult and should only be attempted in the most dire of circumstances. A harpoon must be used and it must be thrown deftly through the water into the beating heart of the yak. Only the most skilled yak harpoon masters will be able to correctly harvest. Once the life force of the yak has been extinguished it will float to the surface of the ocean and if left untended, bloat. To prevent bloating the yak harvest must be swam to the shore of the ocean through the breaking waves in the fading pink and golden light of the setting sun.
Once ashore the yak should be talked to in a gentle voice so as not to disturb the delicate doily of death that has been placed upon it. After a suitable fire has been manufactured and a large hole has been excavated in the sand the yak shall be prepared in accordance with the Book of Yak and Sparrow Preparation.
Do not mourn the death of the yak. By grieving you send a signal to the rest of the oceanic yak herd to come ashore and offer comfort. The day that the herd comes ashore will surely be the end of all life upon the earth, save the yaks. In the past a small child had thought with compassion towards a yak and was eaten by the mother of the yak.
