Snow

Snow is somewhat plentiful, but it doesn't sell for too much. Selling for $10 each, snow can be found on 4 different snow islands located to the left of the Main Island. Although Snow and Moon Dust look almost perfectly identical, you don't have to worry about confusing them, since they are on the opposite sides of the map.

Make sure you bring a Hot Chocolate or a Temperature Stabilizer before trying to pick any up, as the snow islands make you lose temperature at a rate of -1 every 2 seconds, in contrast to the water's -1 every 3 to 4 seconds.

You can pick up snow using any bucket. Despite snow's low sell amount, snow has an important purpose; sacrificing. By sacrificing snow, you can get Condensed Joy (the stats of this sacrifice can be found in Loot Tables) which does the same thing as eating Cosmic Sand. This item can, ironically, get you to the moon and Moon Dust.
