Powder Snow is a trap block that naturally generates in strip formations in Grove and Snowy Slopes biomes, and can also form in cauldrons left outside during snowy weather. It is collected and placed using a bucket.
Entities that walk into Powder Snow sink through it and begin to freeze, taking damage once fully frozen. Wearing leather boots lets a player stand on its surface without sinking, and any piece of leather armor prevents the freezing damage. It also puts out fire and hides mobs and items inside it.
