A genetic mutation occurring with a
cat and a Pop Tart resulting in the ability to have an addicting annoying song, something to
troll about, the icanhazcheeseburger franchise, and making rainbows come out of your butt while flying through the air. The rainbow poop can be turned into monochromatic poop if the Nyan
Cat's diet isn't maintained. His diet is small children and bananas.
Son: "Mommy, why are we putting little Jeffery outside?"
Mom: "We are feeding Nyan
Cat, dear. We don'
t want his
rainbow poop to turn monochromatic."
