Disney is crass and often engages in subtle moneygrubbing. They go out of their way to enhance profits. The drinking fountains at Disney parks are rather well concealed near the restroom doors. This is done to cause the public to pay $2.00 or more for drinks.
But I cannot really fault Disney for portraying a Hawaiian king figure as huge and obese, because Hawaiian nobility were deliberately huge and obese. It is the nature of the art of cartooning to exaggerate the outstanding features of the subjects. Had that portrayed the Hawaiian nobility as Charles Atlas types, that would have also resulted in criticism.
Should anyone venture to the famous Hula Bowl Flea Market in Honolulu, they are sure to note that the Hawaiian and other Polynesian locals are not at all the svelte Duke Kahanamoku types.
It is, by the way, a great place to shop and chat with the locals. Everyone in Honolulu is quite friendly.
