Skullfish

are recurring NaN Enemies in. They are skeletal fish that are similar in behavior to piranhas.

NaN Skullfishs live in the seas around MM:, as well as in the water just outside of the MM: after defeating MM: in. They spawn at certain intervals within the Bay and swim towards MM:, biting him if he does not raise his defenses. MM:'s electrical shield attack can be used to defeat them. In, they can also be caught in the MM3D: by wearing the MM3D:.

NaN Skullfishs appear in the TP:, as well as several secret NaN Caves around TP: in. They can be caught with the TP:, and will even drop a TP: when released, although they are forbidden fish and will not be recorded in the TP:.

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. In this appearance, they are green rather than bone-colored.

There is also a desert variant of this enemy called the TFH:, which instead inhabits the sand of The Dunes, but behaves identically.

In, NaN Skullfishs appear as Weird-type HW:. They are imbued with the Darkness HWDE:. When consumed by a HW: in the HW: of the HW: mode, NaN Skullfishs can increase the Fairy's Trust level and personality traits.

NaN Skullfishs can be found swimming in deep pools of water in. They move to the beat of the music and move every two beats, always crouching within the water for one beat before moving to an adjacent tile on the next beat. 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. Occasionally, they will leap into the air before diving back into the water again.
