My idea is guns, not like modern guns but like something like an old pistol or shotgun. However there is something special about this gun, when you craft the gun (3 iron at the bottom, in the middle row 1 leather in left,1 leather to right) you add 3 of whatever kind of item that resembles a mob at the top right and left and then a dye this will spawn a different color mob (porkchop and blue dye = blue pig) this will drop different colored drops (blue pig drops blue pork) which each have their own use/effect. This will help minecraft by adding something fun to play around with and something that can be helpful for RPGs
