"But...what's up with the red in the background at 0:20? O_O"

If I'm recalling correctly, a January promo revealed Phineas, Ferb, and Candace hanging overtop lava. That doesn't necessarily coincide with the Goozim pictures we've seen - regardless, I *also* remember a different perspective of the Goozim scene as of the E3 preview. Same scene as when they were bounded by the metal chains, but they were placed on a sole 'island' above the lava, about to be eaten.

Hopefully, that should explain it. We'll just have to wait and see, though! : )
