The 3 Tails is a YouTube series about three girls, who turn into mermaids when they find a mysterious cave and read a spell during the half-moon. This show was made by, the Australian TV show, H2O: Just Add Water.

The show even has their very own Wiki!


The show revolves around three teen girls, Jackie, Emily, and Selena, who, after taking a swim in the ocean, find a magic cave. Inside the cave is a spell. They read the spell on the half-moon, and the next day, they realize their mermaids! Within 10 seconds of coming in contact with water, they grow beautiful, long tails.

In the season one finale, the main antagonist, Mia, becomes a mermaid when she follows the girls to the cave, and she reads the spell.

In season two, there is more mermaid magic than ever before! From finding special necklaces, a deadly spell book, to popping a tail at the semi romanticized; Jackie, Emily, and Selena are in for a spin!
