Katara smiled. "It can be pretty common back home. we've had some pretty big creatures, although not all of them are friendly. Appa has been our companion since I've known him: he's linked to the person he sees as his master, but its not even fair to call it that, The two of them have a bond, and as they're both the last of their kind, its even stronger now."

Katara looked a little wistful here.
