Sharky dove into action, using his superpowered toothbrush to scrub away the sugary menace and teach the sea urchins about proper dental hygiene.

As the sun set on Coralgate, residents could sleep soundly, knowing that Sharky was always there to protect their smiles and keep their teeth sparkling.
