1. In Moana, Gramma Tala says that their people stopped exploring about 1,000 years ago. In actual history, there was about a 1,000-year "Long Pause" where Polynesian explorers stopped sailing.
2. When Maui turns into a half-shark, his tiny tattoo version also has a shark head.
3. Whenever Maui transforms, since he isn't holding his hook anymore, the hook appears somewhere in the markings on his body.
4. The Union Jack flag flown in Pocahontas is accurate to the time period. The extra red stripes in the modern flag are meant to represent Ireland, which wasn't part of the UK at the time.
