Snowball is a throwable object that players can collect by breaking snow blocks or snow layers with a shovel. When thrown, it does not deal damage to most mobs but can be used to knock them back or break certain blocks like Glowstone. Players can also use snowballs to craft snow blocks or as ammunition for dispensers, creating traps or mechanisms. During the winter season, snow golems can be created by stacking snow blocks and adding a pumpkin head, which will throw snowballs at hostile mobs.
