The demo version of Bone: Out From Boneville consists of one of the game's opening scenes where Fone Bone (played by you) and his two cousins, the rich and obnoxious Phoney Bone and the fun-loving singing hobo Smiley Bone, ponder as to why they have been exiled from their village. It serves as a tutorial as well.

Along with that, you get a nifty little mini-game where you attempt to escape the wrath of some very angry locusts. The file is a very minuscule 73.4 MB.
Based on Jeff Smith's comic, Bone as a game will definitely receive attention of the adventure game fanatics to a large extent.
