Daisy and Azalea remember their adventures in Beyondness, which they miss very much. The mermaid sisters decide to have some more adventures, and all they need is a map.
Now, that they have no trouble finding the Pink Sparkle, seems it will not be difficult to have a good time. But the sisters do not know that everything will go totally different as to what they have planned.
The new girls on the beach have no idea what kind of surprise is in store for them. While all of them enjoy ice-cream, the mermaid sisters use their abilities to save the day for everyone.
