Chalk + Clay "Pretty Boy"The color of his blue-gray for me it looks like clay, well, probably all the same it chalk + clay! Hard, but easy to chew, muffled crunches, then turns into an oily greasy gruel that stick to the teeth as clay, with no grains like, well, even if there are a couple of pieces, they just lie in the harbor. Generally resembles butter it is a little bit of chew in his mouth and the pieces begin to melt. The smell of milk. When you chew a smell of damp earth, herbs. Very tasty.
