I really wish they'd sell them, too! That would be a great craft idea for the Ranch, as well. They could set up a station where kids learned to make or paint sugar skulls.
Of course, at Disneyland they'd need to sell ones that would be edible, not the sugar/paint ones...otherwise some clueless parent would feed a sugar skull to their kid and argue that since it said "sugar," it must have been food. O_o
