"Oh God," Jenna-in-John gasped, still astonished at the sound of her-er, his new voice, "this is just too weird!"
John-the-mermaid nodded. "Tell me about it. Unfortunately, though, it's all real, and we've got bigger problems than just being in the wrong bodies. I don't know what the mermaid is planning, but she's on the loose with your body and my body-swap ring. If that doesn't spell trouble, I don't know what does. So we've got to-HEY! Pay attention!"
John used one arm to cover her naked breasts, which had Jenna mesmerized. He snapped out of his trance, blushing almost as bright as she was. "Sorry," he muttered sheepishly.
John nodded, rolling her eyes. "It's all right; I'd be doing the same thing if our roles were reversed. Er, weren't reversed. Anyway, we've got to stop her. I can't even go on land, so I guess you'll have to do it. The key, I think, is that you're going to have to get the body-swap ring away from her somehow, which means you'll have to find her and get the drop on her. I dunno, maybe you can knock her out if you get her alone."
Jenna nodded. "I'll think of something," he said. "But I've gotta go, before everybody thinks I've drowned. I'll meet you back here, then?"
John nodded. "Take care," she said. "Bring my body back in one piece, okay?"
Jenna smiled. "I'll do my best," he said.
