Step 2: Carve the body
The first step is to carve your yeti's body. Try to carve it all out of a single brick of tofu, being careful not to make it too thin and flimsy at any point. There's no need for fine detail here; just go for the main features. Be sure to give it a wide, sturdy base so that it can stand up. That is to say, give it bigfeet.
As you can see, nearly all the structure of my yeti's body was concealed by its hair later on. I also decided that my yeti was too short, so added a separate head.
