CANNON is made by splicing FIREPLACE and BLACK BLOCK. CANNON belongs to misc blocks category. Planting CANNON and kicking back is the right attitude. Want 11 experinece points? Brake CANNON block or tree. CANNON can be broken. You get at least 1 seed back (maybe more!) from splicing CANNON. Profiting with this might be questionable. Will you get enough blocks to build something? You just have to find out yourself.
