Unicorn Diet Unicorns in remote frozen areas of necessity have a very limited diet. Stags and does feed primarily on the bark of certain trees and shrub plants, on soft rocks, as well as on the snow itself. Many of the blemishes and pits on boulders are the result not of weather erosion but of unicorn predation. Minerals are much more important to the health of unicorns than are vitamins. Fortunately these minerals are easily obtained. Unicorns of the sea, for example, feed almost exclusively on kelp, which contains few vitamins, is in its natural state indigestible to humans, but is rich in potassium, phosphorus, iodine, and calcium. Sea stags and does also feed heavily on stone, and many of the hollows we see in tidal pool rocks have been eaten away not by the waves and wind but by unicorn teeth. As you can see, unicorns are very limited in the variety of foods eaten by the availability of edible items in their environment. Unicorns of the forest and meadows dine on certain berries, blossoms, buds, bark, farm crops, honey, and sap. Clean washed river stones formed an important part of their diet. Those living in areas where there were caverns were repeatedly seen or heard gnawing on stalactites and stalagmites. Unicorns like most ungulates are quite addicted to certain minerals. Horses are often seen eating earth in which not a blade of grass or a root exists. Hoofed animals obtain some minerals from natural salt licks and by chewing bones. Unicorns, however, have refused and shunned any boned left for them as they are strictly vegetarian.
