Ep 17. Moonstruck

In "Moonstruck," the 17th episode of H2O: Just Add Water's second season, things take a mystical turn when the girls' powers start to manifest in different ways under the light of the full moon. Rikki, Cleo, and Bella each experience strange transformations that leave them even more vulnerable than usual, and they quickly realize that they need to figure out what's going on before it's too late.

For Rikki, the full moon triggers a newfound ability to control and manipulate fire. While this might seem like a cool new power at first, she quickly learns that it's also incredibly dangerous and unpredictable. As she struggles to rein in her flames and prevent herself from setting everything around her on fire, Rikki realizes that she desperately needs the support and understanding of her friends in order to stay safe.

Cleo, on the other hand, finds that the full moon has given her an unexpected boost of strength and agility. While this might seem like a great thing at first, she soon discovers that it also means she's more likely to accidentally hurt someone. When she accidentally uses her newfound strength to knock Bella unconscious, Cleo is wracked with guilt and begins to wonder if her powers are more of a curse than a blessing.

Finally, there's Bella, whose water powers start to behave in a completely different way in the light of the full moon. Instead of simply controlling water, Bella finds that she's now able to manipulate it in even more complex and intricate ways, allowing her to do things that she never thought possible before. However, as her powers grow more and more out of control, Bella becomes increasingly afraid that she'll be unable to put them back under her control.

As the three girls struggle to come to terms with their new powers, they start to realize that they need to take action before things get even worse. With the help of Lewis and Will, they set out to find a way to harness their abilities and use them to save the day. Along the way, they encounter all sorts of challenges and obstacles, including a group of mysterious strangers who seem to be intent on harnessing the girls' powers for their own purposes.

In the end, the girls are able to overcome these obstacles and defeat the forces of evil that threaten their town. With their powers once again under their control, Rikki, Cleo, and Bella are able to breathe a sigh of relief and return to their normal lives. However, they know that they can never let their guard down – after all, who knows what other strange and unpredictable abilities might lie in store for them in the future?
