N. A bun bun is a peculiar critter with many idiosyncrasies. Generally female, Bun Bun's roam the wild generally carrying around large purses, and not wearing pants. Though being creatures with abnormally disproportionate heads, they are swayed and ruled by the demands and edicts of they tummys. After eating a meal, Bun Bun's generally convene again at the dinner table to partake a second meal of fruit. Despite all this they maintain a perfect figure. Bun Buns in their natural habit are suberb fashionistas, they work like elves with little sewing machines even though there may be huge opportunity costs involved such as lack of sleep or loss of weight. They are known to sleep in other peoples cars and are easily spooked by popping balloons. Wild Bun Buns are commonly seen wandering downtown, lost with no sense of direction, however more cultivated Bun Buns easily navigate the labyrinth streets of the city. For sustenance, Bun Buns are seen scurrying to and from Starbucks, which they peculiarly call buckstar. If one ever encounters a Bun Bun, domesticated or wild, proceed with caution
Its a wild BUN BUN in her natural habitat, Best not disturb her while she sleeps.

A main character in the webcomic "Sluggy Freelance"
He's a little white mini-lop with the attitude of a homicidal gangster. Favorite weapon is a switch-blade but also has a gun (where all this is stashed in anyones guess)
