A 12-second anime opening, inspired by famous anime battles showing an epic swamp battle between an army of ninja frogs and a massive heron boss warrior. Dynamic camera movements with sweeping aerial shots, close-ups of determined frog warriors leaping through mud and water splashes in slow motion. The giant heron stands tall like a samurai, wielding a glowing katana with graceful but deadly moves. Explosions of water, mist, and lightning flashes illuminate the chaotic swamp battlefield. The frogs perform synchronized attacks using shurikens made of lotus leaves. Fast-paced anime-style editing, intense lighting, epic orchestral rock soundtrack with drums and choirs. The tone is heroic, over-the-top, and slightly comedic — pure anime energy
