Fungo Squiggly is an anthromorphic ferret in Darby Conley's comic strip Get Fuzzy.

When a new family moved into the apartment next door to Rob Wilco, they introduced Fungo as their pet. The amiable Satchel Pooch made friends with the newcomer easily, but Bucky Katt immediately regarded him as a mortal enemy. Although he whispers in Satchel's ear on occasion, Fungo does not speak out loud in the strip.

Bucky's attempts to defeat and/or humiliate Fungo almost invariably backfire rather badly. For example, Bucky once tried to trap the ferret in a crude snare. Fungo yanked on the rope, causing Bucky to smack into a wall and lose two teeth: his trademark cuspid and a smaller tooth. To add insult to injury, Fungo wears the smaller tooth on a necklace. (Bucky's "fang" was reattached at great expense.) Other plots have had similarly unintended consequences, such as Fungo's kidnapping of Bucky's beloved toy Smacky.

No explanation is ever given for Bucky's intense hatred for Fungo. Bucky may mistake the mustelid for some sort of rodent, or the enmity may be as inexplicable as his desire to consume a monkey. Perhaps it is simply another by-product of Bucky's boundless hostility towards the world in general. In any case, many (but not all) of Fungo's aggressions toward Bucky are simply reactions to the cat's attempted assaults.
