Has anyone else realized that Runt was played by a women this whole time?

Yep. Most animated characters are voiced by women outside of the movie theater industry.

Everyone's known that since the second movie.

He's not the first male character in an animated movie to be voiced or portrayed by an actress. There's Mumble in Happy Feet and Erik in its sequel; they're both voiced by Elizabeth Daily when they're chicks.

I've probably seen plenty more, but Happy Feet is all that comes to mind right now.

i never knew that.

I joticed it a the first time watching AaO 2. I saw the credits at the end. But I think Kate Higgins did a pretty good job voicing him, but I would think it would be harder to change a female's voice into an animated male's voice. Alas, I could be wrong.
