its a snowman from minecraft,it looks like 2 snowblocks stacked and a pumkin on top, you can also right click using a shear on its head to reveal its snowhead which are just a snow with and some dots for its mouth and its eye, it is a passive mobs meaning it dosent attack the player even if the player does, the snowman also throws snowballs to monster but it seems like it does 0 damage and only some knockback.. snowman is also weak to a hot biome/dimension such as a dessert and the nether
