This release is called "surfacing" because all four of these mermaids have made their way to the surface for some above the water fun. And the unique twist to these mermaids is that the PNG files for each come as two separate images, the torso and the tail, so that you can have fun playing around with the placement of each. And the tails can even be mixed and matched between three of them.
Finally there is Nerida. This carefree mermaid is taking a cue from the otters she has seen and has lain back to relax on top of the waves and just let the current take her where ever it will. What a relaxing way to spend an afternoon!
