So apparently Disney slacked off when they made "Moana," because there's an inconsistency in Tamatoa's song "Shiny" when he says 'But you can't expect a demigod to beat a decapod (Look it up)' however just one scene earlier, Maui claims tthat Tamatoa is pissed at him because ripped off one of Tamatoa's legs. Also, deca- means ten, but since Tamatoa's got a missing limb (with limbs including his claws, of course), he should be referring to himself as a NONApod, since the prefix nano- means nine.

Other than that the movie was awesome! Props to Disney!
