Magic

A mermaid with green hair and a green tail gazes at a glowing, swirling green light in the water, then crosses her arms with a concerned expression as the light intensifies. The scene cuts to a close-up of the light, then reveals a green-skinned, white-haired sea witch with a malicious grin, holding a golden seashell. The sequence ends with a woman with red hair and a red top, looking down and smiling slightly, with a small inset image of a woman in a black top.
