Drum and Bass, 172 BPM, aggressive breakbeats, heavy sub‑bass, dark cinematic atmosphere, liquid DnB melodies layered with neurofunk textures. Add sound design elements: ocean waves, wind, distant cannon fire, creaking wooden ship, seagull cries. Use dramatic crescendos and sudden drops to reflect the pirate battle and shark attack. High energy, intense, epic, adrenaline‑fueled. No vocals (instrumental only).
