Frozen, one of the most successful Disney animated films of all time, has inspired a multitude of fan theories that vary from reasonable to downright ridiculous. One recent example takes real-life science and applies it to a movie where a queen can alter thermo-dynamics of nature itself.
The theory focuses on Sven, the reindeer companion of Kristoff, and clues about his character that might darken the sunshine and joy offered by this modern Disney classic. By looking at the life cycle of real-life reindeer, the theorist unravels a potentially dark and depressing side to Frozen.
The theory, posted to Reddit, uses what we know about reindeer antlers and lifespans in the real world to conclude that Sven is female. And, sadly, does not have a lot of time left.
The theory establishes that reindeer antlers are shed at different times of year depending on the sex of the reindeer. Male reindeer shed their antlers in mid-December, while younger male antlers shed them during mid-spring. Female reindeer retain their antlers until the summer.
Because Frozen primarily takes place during July, it is clear that Sven must be female. The only problem is this stands in direct contradiction to all official material offered by Disney.
Still, maybe Disney ought to reconsider what Sven's sex is, since the theory goes on to explain that male reindeer tend to die very young due to their aggressive lifestyles. The average lifespan of a male reindeer is five years, with some managing to live up until 10. Female reindeer live up to fifteen.
But don't feel too optimistic yet about Sven's life, since that means that, judging by how Kristoff knew Sven since he was a kid, Sven must be nearing the end of her (or his) life.
Like many fan theories, this one takes the real science of our world and applies it to a fictional one that doesn't adhere to the laws of ours. Disney films are hardly scientifically accurate. Some have featured fish with gills flopping around on land for extended periods of time without struggling to breathe and flowers that can restore youth.
The idea that Sven must be both female and almost at death's door does not jive with the magical realism approach Disney takes with their animal companions. Disney critters are never truly realistic. They emote and have personalities not unlike people. Sven is no exception.
This means that real life science shouldn't be applied to Sven. It's perfectly possible that Frozen's reindeer have different biological functions than real ones. After all, rock trolls and magic snow don't exist in the real world. Why should the life cycles of reindeer be any different?
Assuming this pseudo-science is true, perhaps we can brush over the flaw in Sven's antlers. But what about male reindeer dying young in general?
Sven spent his entire life with Kristoff. It is highly possible that, because of this, the naturally aggressive life patterns most reindeer undergo didn't materialize in Sven. Which means that, maybe, because of Kristoff's nurturing, Sven's violent nature never materialized.
Regardless, that doesn't mean Sven has much time left. Assuming Frozen 2 takes place even two years after the original -- or even a few months -- that brings us closer to the inevitability that Sven will probably die of old age pretty soon. This is Sven's last adventure by any metric. (Unless Sven stumbles upon that magic flower of youth...)
Or, as the theory jokingly suggests, Kristoff could just have multiple reindeer who are all, for lack of better imagination, named Sven.
