Hei Hei Is a Demigod
You may have thought that Hei Hei from Moana was just a particularly bird-brained pet rooster. However, this theory makes him so much more than that. Much like Mushu from Mulan, fans suggest that Hei Hei is actually a demigod sent to keep Moana safe. The evidence for this theory is basically that Hei Hei keeps surviving when he should die. On top of this, he never seems to age and looks the same in scenes where Moana is a small child. Compelling!
