Blue Hawaii is a type of cocktail made of rum, pineapple juice, vodka, and a sweet and sour mix. It is a tropical drink that is blended with ice to make a frozen cocktail.
"A "shaved ice" version of Jack Frost created by the genius thaumoscientist Dr. Thrill after he moved to Japan. He absorbed Japanese pop culture and took a liking to hero groups and shaved ice. It is unknown whether he actually tastes like a Blue Hawaii."
"One of the "shaved ice" subspecies of Jack Frost created by Dr. Thrill. Its official name is "Blue Hawaii Frost." Having sought asylum in Japan, Dr. Thrill was soon exposed to a great deal of Japanese culture, and, upon buying a variety of sentai masks and shaved ice at a summer festival, was inspired to create this variation of Jack Frost. Whether or not they actually taste like "Blue Hawaii" has yet to be determined... though admittedly, what "Blue Hawaii" even tastes like is a mystery in itself."
