Harry expected that he would run out of air very soon, but then he realised that he could breathe. He had gills just below his ears, and his hands and feet had formed web-like skin between them to create flippers. He also realised that he could see quite clearly through the murky water, and that the cold didn’t bother him at all anymore. Harry had become some weird human-fish-frog hybrid, and he dreaded to think about what he’d look like in the mirror right now.
