What if Tamatoa was actually beautiful under all that bling?
Or, to elaborate, what kind of self-hatred would compel him to cover himself? Why 'drab' when he's clearly not?
The inability to love oneself for what they appear to be, the racial 'ugliness', recalls me of one of my favorite ever books: The Bluest Eye. In the case of Pecola, she saw salvation in blue eyes. Tamatoa sought to escape his being 'just a crab' by covering himself in gold. In both cases they wound up a leeeetle nutso.
