Snow

Snow, is a white and very soft material the Pigs use for their forts on Season's Greedings along with Clouds, from Hogs and Kisses. It is easily destroyed by any bird, and any bird can destroy any size of snow blocks. Unlike most materials pigs use, snow is not affected by gravity, and can hold things up in midair. If the snow is destroyed, however, holding a large portion of a structure, the entire section will come crashing down. Snow is also destroyed when an object too heavy for it falls onto it. It also does not have a "damaged" state, it only is on the screen, or gone.
