You have decided upon one bottle of shampoo termed "Ocean Scales". It's got a detailed drawing of a mermaid upon a rock with waves combing her long luscious locks with as much delight as if she had an orgasm. She showed her arrogant chest too. The brands must be European, where sex and especially breasts are not deemed such a taboo. And perhaps potential customers will assume that the shampoo guarantees not only golden locks but also big boobs, thanks to some sort of magic. But the bottle IS nice and indeed it smells divine. You really have the impression of being on a seashore. You decide to try out the bottle as soon as possible, indeed at your home. You want to splurge a little more and you organize yourself a warm luscious bath, complete with candles, foam, staggering mounds of bubbles and you dip in, moaning in delight as you slip in the warm water.
And the shampoo is as scrumptious as it promises. The liquid is blue-green with golden shimmers and the smell permeates the entire bathroom. It really feels as if you are in a sun-kissed ocean. To rinse off the shampoo, you dip back under the water, happy to delay the final rinsing to later through a shower. But as you literally float in aquatic bliss, your chest tightens and your legs ate seized with sharp pain. Your throat hursts, your neck too and you gasp only to release bubbles, your eyes seeing only soapy water, of course all blurry. You clutch your throat as the pain intensifies and each second feels like an hour. What is this? What's wrong? Are you going to drown? In your bathtub? But as soon as it started, the pain vanishes and a muscle spasm catapults you to the surface. You break said surface, breathing again. Then you see your own reflection in a mirror and you realize with incredulity that you have become a mermaid, your tail rising up lazily behind you and displaying itself to your own wide eyes.
