Kristoff Wears Sven’s Mom
When we first meet ice harvester, Kristoff, in Frozen, he is seen with a young Sven. Sven’s mother was killed by ice harvesters, according to this theory, and her pelt was turned into the coat worn by little Kristoff (and later older Kristoff).
This would explain why Kristoff and Sven are so close, which is creepy. Kristoff not only raised Sven, but he did so while wearing his mother’s skin. Scandinavian cultures are known for wearing reindeer pelts as clothing.
Bing Bong Works for Monsters, Inc.
