I'm in the business of finding good movies for my little brother (he's 5). And I remember watching some animated movie on TV one time, long ago, and I remember thinking that it was awesome, but I have no idea what the name of it was. It's about rats. I think something about good rats fighting evil rats. Either that or rats being threatened by human machines plowing the field above ground (the rats had a network of caves and tunnels underground, i think). Or maybe there were elements of both. And I'm also pretty sure there was also magic involved. I think there was a very old rat who was a prophet or something. And I think there was also a crow character or even two. And that's pretty much all I remember. It really was a long time ago, probably more than 10 years.
