The emperor penguins have been spared extinction only temporarily.Happy Feet took its cues on penguin behavior, pre-Mumbles, from March of the Penguins — both the French and the English editions. But anyone who's seen March of the Penguins knows that there are good reasons for the old traditions. Don't worry, this isn't a Shaggy Dog Story (of either kind). Mumbles's actions help the food supply, not just of emperor penguins, but of every non-human species that eats fish or the ingredients of "fun food." The whole ecosystem had suffered; the whole ecosystem will be repaired in part. It's just that the Law of Unintended Consequences is inescapable.
The film is a metaphor for losing faith in a religion. Mostly.
The film is a coming out story.Unfortunately, Executive Meddling prevented the true ending from ever seeing the light of film projectors.
The true ending that got cut involved alien abduction and resources being drained from the Earth in a Combine like plot.That would have Unfortunate Implications for either gays or closets.
The film is a metaphor for mental disabilities.Hey, Mumbles was dropped as an egg! Since it is a Hollywood film, the metaphor is the usual Hollywood version, just on a grander scale. The mentally disabled, because of their disability, are pure in heart. And because they are pure in heart, they can do great things... yes, they can even save the world!
The sequel's aliens will be actual aliensOkay, so we don't see any aliens in the sequel. But if we did, then they would. Or maybe they'll be in ''Happy Feet III.''
Eric has problems with the cognitive distortion catastrophizing.Given how he overreacts over everything (to a ridiculous extreme), that would explain a lot.
Erik is adopted.Mumble looks like he never fully matures, which might mean he was sterile. Maybe Erik's birth parents died while he was still an egg, and Mumble and Gloria chose to raise him since they couldn't have a chick of their own.
