One of the most authentic areas on the beach was the Japanese sushi stand as dozen of people go there to enjoy a very edible platter, or plate of sushi made by some very professional chefs known by dozens to be very popular with the food. Who didn't like eating rice, fish, and veggies all at once at the beach.
However what is unknown to the people who order at the sushi is that the chefs weren't exactly normal, because they have a special seasoning that each and every customer who orders the sushi decides to eat. While the seasoning is in the food for the customers to eat, the mermaid virus kicks in, because that is what in the spice for the people who will eat the rolls. In truth, the employees of the sushi stand are secretly women as they sometimes disguise themselves as men.
