Note: This was done in Beta v1.8. A player can grow mushrooms with bone meal (crushed bones from skeletons), with the brown mushrooms producing raised platforms, and the red mushrooms producing small shelter-like structures. Provided the room is available, and you have killed some skeletons, the brown mushrooms can be used as a flat area for an even base, while the red mushrooms provide shelter from mobs. As the red mushrooms leave some area open, it is imperative that the player cover this with another material. Once set up, glass panes or blocks of glass for windows can be added as viewports, and a bed can be placed to sleep in. As a home-building material, it is semi-reliable, but requires some skill and luck to make a home out of mushrooms, as the use of bone meal grows huge mushrooms unevenly, with the mushroom stem growing one or two blocks higher than the lowest possible growth. Huge mushrooms of either type will yield more mushrooms of their respective color, with broken blocks yielding up to two mushrooms, and with a possible fifty one blocks for red mushrooms, chances are very high a player will yield more mushrooms than they had grown, making one huge mushroom good starter for more small homes and rooms made with them.
