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

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.

Drawing helps Will remember he lost his torch on Mako, so he decides to return there. It's a full moon, so the scared mermaids spend the night together at Cleo's.

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.

Cleo discovers a comet is causing fish to flee the waters around Mako Island.

Bella wishes to ask Will to come with her to the big party, but a misunderstanding ensues when it seems he's asking Rikki.
