Evil snowman like mobs

I have a idea for a group of snowman like mobs like the snow golem but doesn't defend the player but instead attack them, they appear different from the snow golem is that they don't wear something different from pumpkin on there head or they have a mean looking face , all of them drop snowballs upon death 

Snow Lobber: lobs a large snowball that does splash damage has a angry face instead of a derpy smiling face, it spawn randomly in snow biomes though it is uncommon or in snow packs 

Snow burrier: spews out snow that can create snow block which can suffocate mobs , it has , it spawns uncommonly in snow biomes  or in snow packs 

Snow squire: wields a wooden sword to slash at player wears a white dyed leather helmet with no mouth , spawns uncommonly in snow biomes or in snow packs also has a 8.5 percent chance to drop a wooden sword 

Snow wizard: fires icicles at players which causes the slowness debuff and a ice particle attack that summons particles that damages and causes slowness, has a icey beard , spawns by itself on top of a gold block surrounded by wooden stairs and drops ice shards that is used to craft ice boots which can make players create snow whenever they walk and a immunity to slowness 

Snow packs are uncommon and have atleast 3-5 evil snowmen
