Sawtooth the Mermicorno sharky! 
No longer the grumpy "yes-fish" flunky, Sawtooth grows genuinely warm toward the Mermi‑Crew. He becomes protective, empathetic, and even tender—like when he shields them from Squidians or hesitates in battle, his heart clearly pulling him toward kindness. The spark of creativity reignites in him after he rediscovers music. Working with Penny, he crafts a song that frees Shelly and defies Ika's darkness—embracing a sense of purpose through melody and rhythm.
