Rikki is frustrated by the water attacks and goes to Mako Island on a full moon to confront the strange force in the Moon Pool, but Will pursues her while Cleo and Bella are delayed.

Zane resents Will having become part of the team but fails to make the girls doubt his reliability.

Zane already hired Will's somewhat haughty sister Sophie for the job in the café Rikki wanted to give Bella, who doesn't really care after all. Dan introduces his girl-friend Samantha Roberts to his daughters.

Will is delighted when Bella brings him a rare deep sea fossil. He invites her to come discuss it and her music at his boathouse, but she runs when he keeps asking about her water-phobia and other quirkiness.

Rikki receives counterfeit money at the cafe and is held captive by criminals on a boat. Bella and Cleo are forced to reveal the trio's secret so that they can rescue Rikki.

Laurie's Dolphin Rescue needs funds, so Will and Bella think of a rock benefit.
