NaN Skullfishs are found exclusively in the TFH: in. They viciously attack any TFH: they find swimming near them, and will leap out of the water to get to TFH: standing on raised platforms. To defeat them, they can be slashed with the TFH: while they leap over a TFH:, or dredged from the water with the TFH:. They can then be attacked as a normal enemy.

NaN Skullfishs can be found swimming in deep pools of water in. They will typically try to attack CoH:, CoH:, CoH:, or CoH: at close range. They can be lured into shallow water, where they will beach themselves and flop around helplessly for seven beats before they jump back into the water.
