Moon Spell is the 7th episode in Season 1 of H2O: Just Add Water.


The spell of the Full Moon turns Emma into a carefree, wild mermaid. At her father's birthday party she's the opposite to her usual, organized self. Can the other girls stop her before all is revealed?


Emma is bustling about, trying to arrange the party for her dad. Cleo and Rikki stop by and find her in a right state of fussiness that bothers Rikki. Later, Cleo is working when Miss Chatham appears and warns her not to look at the full moon or its reflection, also she reminds her not to touch water because it is dangerous before disappearing Chatham a as Emma and Rikki arrive, leaving Cleo worried.

That night, at the party, everyone is there and Emma is getting a drink when she sees the full moon and transforms into a wild girl! She offends lots of people before Cleo takes her outside. But Cleo leaves her so Emma jumps into the sea and swims to Mako Island. When she comes back, she pulls Lewis in with her! Rikki tries to dry her, but Emma can't transform!

They put her in the spa and ask her to stay. But after they leave Byron comes past and Emma flirts and kisses him. Elliot sees this and alerts Cleo and Rikki and they break them up. Lewis comes with Grandma Gilbert's wheelchair and they sneak her away. But Emma causes even more trouble-freezing Zane and Miriam's lips together and pinching Byron's butt! Everyone wants to hear Emma's speech, but she's eating all the food before eating time so Cleo improvises one. Soon, people begin leaving because Emma ate all the food for the party so the girls and Lewis take Emma to JuiceNet, where she turns back into a human the following morning. The wild girl goes home and apologies to her dad before going back to the JuiceNet and discovering she kissed Byron! After he tells her that she has the world's best lips.

Byron: (to Emma): You have the world's best lips!

Emma: Harrison, you have a lot of nose hairs. It's a real forest!

Emma: Aunt Thea, that skirt - did you borrow our picnic rug? Haha!

Cleo: I can't help thinking about what that old woman said. 'Beware the full moon...'
Rikki: We're mermaids, not werewolves.

Emma: (grabbing someone's water bottle and pouring it on the ground): I just love the look of water.

Emma: Have you ever thought about how weird people look? Their legs just don't look right.
Cleo: You need to sit down.
Emma: Now, take fish: they're sensibly designed.
Cleo: Can I get you anything?
Emma: I'd love a cheese sandwich...on rye bread..with sardines......actually, forget the cheese and the bread. Just bring me sardines!

Emma: (in the water): Come to Mako Island with me. Its a most wonderful place. It's like an underwater wonderland. We can all live down there forever. (a loving sigh)

Emma: (Rikki having dried Emma, but she is still a mermaid): I like my tail just the way it is. I think its perfect!

Candy: I beg your pardon.

Emma(to Elliot) That's wrong; we can't have black balloons.
Elliot: Sorry.
Emma: It's a party, Elliot...happy, cheerful!
(Rikki walks in)
Rikki: Welcome, to my gothic world!

Harrison: I'd have a big lunch, eight hours ago.
