The 水月怪 is a 困難模式 敵怪 from the 日食 事件. They attack like most other fighter-type enemies on land, but Creatures from the Deep also have the ability to swim. While they are in water, their speed and maneuverability increases dramatically. It is also capable of jumping out of the water towards the player, doing so with maneuverability similar to a 獨角獸.
- The Creature from the Deep is a reference to Gill-man from the 1954 movie Creature from the Black Lagoon.
- If it is forced through a 2 block high space, it will stand with its arms down for a few seconds and then start moving away from the player.
