I was watching the brain freeze clip for the 5493th time, and I finally figured out where I'd seen the horns on the skull before. They're the same horns that Doofenshmirtz's dad has on his helmet.

And I think I've figured out most of the plot of the movie now, but it doesn't make me any less excited for it.
