They have little life, add some more? as he has 2 hearts, increased to 5, please, and as he does no damage, can the snowball cause this half heart damage? but the snow golem's snowball can slow the enemy down (in fact, its snowballs cause slowness level one in enemy). They could also release particles at a certain time and swim in groups of 3 or 4 normally in snow biomes, and when it is in a (cold biome), it gains level 1 speed and regeneration also at level 1, when it is in normal temperature biomes, it has no effect, when it is in very hot biomes (savannah, desert), stay with slowness level one.
