The girls prepare for the full moon again and insist they don't need Lewis' help. Rikki and Cleo suggest Ash to be more bold with Emma. Following their advice, Ash decides to do a surprise visit which could uncover their secret.

Under the guidance of Cleo and Rikki, Ash asks Emma out and ends up bringing dinner to her house just in time for a full moon. Cleo and then Rikki fall under the spell of the moon and trick Emma into coming upstairs where she falls into the bathtub and turns into a mermaid. Lewis has to try to stop Ash from discovering the girls' secret.—Anonymous

Unable to convince Emma to tell Ash the truth about herself, Rikki and Cleo encourage a wounded Ash to be bold, but his first romantic gesture couldn't be timed any worse than the night of the full moon. Without Lewis to help, the moon's power quickly takes hold of the girls whose odd behaviour is witnessed by Ash. In the light of day, and with little memory of the previous night, Emma has a big revelation for Ash.

Unable to convince Emma to tell Ash the truth about herself, Rikki and Cleo encourage Ash to make a bold, romantic gesture to her. But he musters his courage at exactly the wrong time, when he cooks Emma a surprise dinner at her home on the night of a full moon. By leaving the front door open, he doesn't realise the chaos he is about to cause, when Cleo accidentally looks up at the moon. The mischievous, moonstruck Cleo then forces Rikki to see the full moon, and the two of them plot to get Emma wet, so that Ash can see her in mermaid form. However, Lewis shows up, preventing Ash from seeing Emma as a mermaid.

It's full moon and the girls insist that they don't need Lewis to assit his help as all three girls are staying at Emma's and Ash is coming over. When Cleo and Rikki fall under the moon spell, can Lewis stop them from revealing their secret to Ash?
