Visually, the moon turns into a snowman, though remaining in its current phase. It is similar to the Pumpkin Moon event, but is more difficult, and (Old-gen console and 3DS versions)has more waves. During the event, unique and highly difficult enemies spawn at high rates and attack the player. It can be summoned any time of year and does not require the actual Christmas season. The Frost Moon is a Hardmode, post- Plantera, Christmas-themed event summoned with the Naughty Present any time at night, ending at dawn (4:30 AM).
