Will and Bella discover they're the new kids in school. He's determined to return to Mako island and search for the cave entrance to find out what happened to him.

Zane has a surprise, his dad bought the café and made him manager. He renamed it after Rikki, whom he makes a full partner.

It's Valentine's Day. Belle, who can have any other boy, dreams of Will, who is concentrating on athletics and biology, oblivious of her romantic thoughts.

Lewis wants the tentacle-potential cave water safely disposed of, but the girls can't resist experimenting further behind his back. Will, who has a school assignment appointment with Bell, is painstakingly kept away.

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.

Cleo applies for the vacant job of assistant dolphin trainer, despite the water splashing risks.
