Mrs. Quack Quack
A quack quack (duck) from the mind of SRP ASMR. She is a very elusive quack quack that only the most perceptive can see without and illuminated handheld magnification device, or some other visualizing tool. She is often depicted as a duck shape on a board for eye tests, and always the hardest level. Her husband, Mr. Quack Quack, is much easier to see, and featured much less.
"Can you see Mrs. Quack Quack?" "No, I don't think I can."
