There is a fair number of captions that take place in some sort of old fantasy setting, and often they just don't do much with it. So, here's a challenge:

We have a pair on some kind of adventure in a fantasy world of some sort. Let's say one or both of them was originally male. For the caption, try to tell about more than the change itself; try to tell a little bit about these people and their adventure. I'm not asking for an entire story, but at least dabble a bit in what they quest for, and why.
As for the cause of the change, you're free to use some of the more cliche things like the girdles of gender or magic springs, but it would probably be more impressive if you came up with something more original.
(I don't really consider this a group since it's only two...)
