Will orders a mono-flipper, which allows him to dive almost like a mermaid. He accepts to form a private study group with Bella, ignoring she imagines that virtually makes them a couple.

Rikki and Bella hide out at Cleo's to protect themselves from a full moon water attack. Bella's kidnapped by a water tentacle and taken to Mako. Lewis tries to keep Will away.

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.

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.

Sophie and Ryan damage the Moon Pool in their efforts to obtain the rare crystals. Rikki, Cleo and Bella graduate with a surprise.

The girls must face final exams and avoid a water attack in public when the full moon rises early.
