Somehow, a finizen happened to meet a regular dolphin, despite each not existing in the other's world. There was only one thing for it; prove which of them was better, through a breath holding contest. With cheeks and lungs packed with air, they waited to see who would surface first.
Almost half an hour in it started to become clear who'd be winning, the dolphin gaining a blue blush as their cheeks grew to the size of their head and they held their mouth shut with their flippers. The finizen was doing a fair bit better, with only a purple blush and somewhat smaller cheeks that they playfully poked at to tease their opponent. By now, the question had become "Is the dolphin going to inhale before or after they surface?"
