If the banana's blue up, it will be Blue Java. I don't think it's the "Ice cream"/Namwah (USDA "Fougamou 1") because the fruits individually meet the peduncle at a knuckle. Namwah fruit hands meet the peduncle by joining to a pad first.
If the fruits do not turn any more blue, then it would be some form of Bluggoe (Orinoco types).
