What's it about?

Knowing Disney sequels (and seeing some thread titles on here) it can't be anything good, but I'm just wondering, hwat's the actual plot? I don't see how you can make a sequel to fox and the Hound :P then again, I didn't see how you could make a sequel of Lion King, Little Mermaid, Mulan or Peter Pan either, yet they managed... if you could call it that.
