The Christmas Monster creates an immensely cold cloud of ice that will damage all players who walk in it. All players who enter will also be given slowness, by contrast, the Christmas Monster will be sped up upon entering. This cloud will persist for roughly 60 seconds before dissipating.
The Christmas Monster creates a powerful cloud of snow around its current position. This cloud of snow damages and applies slowness and weakness to all players who get caught in it.
The Christmas Monster spawns a magical ball of ice that will hover in one place and shoot projectiles at the nearest player. These projectiles will apply slowness and deal damage.
The Christmas Monster immediately spawns 3 mimics at its current location. The mimic looks very similar to the Christmas Monster, but is far, far weaker.
Upon death, the Christmas Monster will drop a Present (or three if you killed the Diamond variant). This present is full of lovely goodies, some practical and some decorative.
At the present moment in time, there are no commands that can be run by the player. This will change in the near future.
