Rubberduckzilla is the mascot for Japan's "Oasis" bottled beverage, which is billed (get it?) as the drink for "people who don't like water."
I would normally, at this juncture, point out that green tea is a much healthier alternative, and is great for people who do not like to drink plain water, but then I would not want to incur the wrath of Rubberduckzilla:
