Moonwalker is 13th episode in Season 2 of H2O: Just Add Water.


The revived Sertori family camping holiday is ill-fated, not just by choice of location, Mako Island, but in the unfortunate timing of coinciding with the Full Moon. Cleo's friends and Charlotte tag along to help one another stay out of trouble but Lewis' plans are soon tested. Later that night, Lewis and Charlotte go for a romantic walk. Discovered Charlotte's disappearance, Kim opens the "moonlight proof" tent, causing Cleo to get affected by the moon. Kim finds Lewis and Charlotte, who almost kiss. Lewis takes Kim back to the camp, leaving Charlotte alone. Emma and Rikki eventually discover Cleo is gone. Despite Lewis' protests, they leave the tent and face the powers of the moon. Charlotte bumps into Cleo, and then makes fun of her because she thinks Cleo is jealous of her new relationship with Lewis. Angry, Rikki, and Emma, who are watching nearby, strike the ground near Charlotte with lightning. Scared, Charlotte runs away and finds the Moon Pool, which may have unforeseen consequences. The girls defeat the power of moon, and Emma freezes the Moon Pool so Charlotte can't become a mermaid. Lewis arrives and brings Charlotte back to the camp. The next day, the girls and Lewis have to find out Charlotte is a mermaid or not. Lewis "accidentally" squirts her with his drink to find out, but nothing happens beyond her getting wet and upset.


  • Second time the mermaids remember what was going on while under the moon spell.
  • Charlotte discovers the Moon Pool for the first time.




Lewis: She's clear.
