I got an idea. More tamable mobs that are common household pets. but, cats and dogs(wolves) are similer animals and there isn't much veriety. Maybe fish and birds? A mean, fish gives veriety cause they are one of the animals that swim. And Birds fly. I don't know how they would work however. Especially fish cause they can't walk. Maybe when you fish, there is a rare chance a fish mob comes, you tame it(or maybe kill it) and then it drops a tamed fish and you use it like spawner eggs. Put in water, and they attack hostile mobs in there. or maybe Fish could walk on land(although that would be bazzare). And birds would just peck mobs and float there in the same hight as normal players, not using hight as an advantage. as if it were not flying but the bottem of it is invisable. Or maybe they could fly but they can't attack until they reach ground.
