Piranhas are hostile sea enemies that spawn in Second Sea and Third Sea across Danger Zone 1–6 in Third Sea. They appear in groups and typically engage players during travel or while moving through open water areas, making them a constant hazard in unsafe sea zones.

Piranhas are aggressive sea enemies that spawn in open water and attack both players and boats. They can leap out of the water and use biting attacks and electric shocks, and when they hit a player they can temporarily disable dashing, jumping, and ability usage, making movement and escape difficult during encounters. They prioritize targeting the player over the boat, cannot be damaged using M1 attacks from fighting styles or swords, and will despawn if they move too far from their original spawn point, limiting how long they can chase a target.

Drops:

Piranhas drop Electric Wings (1–3) along with $2,500–5,000 when defeated. They grant 5,000–6,000 EXP in the Second Sea and significantly higher rewards in the Third Sea, ranging from 90,000–105,000 EXP, making them a more rewarding source of experience in higher level areas despite their annoyance during travel.
