Snow golem variants + natural spawn (hunt n farm update)

I believe that snow golem should spawn naturally without pumpkins on their heads and could vary in their designs, some could have 2 sticks for arms or some could have 1 or no arms, they could also vary in height, say 1 block tall or 2 and possibly a rarer 3 block tall snow golem. Golems wearing a pumpkin should be linked to the player who places the pumpkin on them, possibly like dolphins when the player is close to the mob, the mob begins to follow them for so long. Perhaps not all snow golems attack mobs with snow balls, maybe some could be scared of mobs and flee from them, or some could stand still in the way axolotls play dead, and mobs wouldn't attack the golem whilst in this state.
