Puffy the pufferfish wants to join the Tide-watch but he’s seen as dangerous, unstable and toxic so isn’t trusted. When he gets nervous and puffs up it’s seen as proof of the stereotype. He’s always told to deflate outside and nobody wants to be his friend. He meets Algwyn the algae who’s always underestimated and treated as a lower life form. They make an unlikely friendship and when playing in the sand one day uncover a ring of jellyfish tampering with the water flow to make the mudskippers seem like dirty creatures. After exposing  the conspiracy Puffy is allowed onto the Tide-watch with Algwyn as his partner.
