Season 2

Phoebe and Jenny are set to know all they need to know about mermaid magic. But when the water starts to attack them, they realise they missed something. While they are dealing with the water, new mermaids arrive. Jenny has been chatting with a lot of mermaids on Skype, and one called Kim (Anna) has been attacked as well. Even Phoebe had been attacked, so if they don't have their necklaces on, they are in a lot of danger. Jenny is the only one to take it seriously. After they meet Kim in real life, they discover a few new facts.
