Billy swam alongside her, glad to finally be swimming passably in the water. He covertly studied her movements, trying to mimic the proper way to do things.

I don't see much appeal in being a slug, he wrinkled his nose, swimming down to the more plentiful areas with her. There were sights far more attractive than slugs there.

If only I had an underwater camera, he whispered, an awed look on his face. The sights were definitely beautiful. He flitted from studying anemones to coral to...wait, there was a fish tickling Katara's nose? He couldn't help but laugh, smiling at one of the schools passing by.

You're such a natural that even the aquatic life loves you, he winked, yelping when another few fish brushed against his tail. Uh...pardon me, he called to them.
