The shmoo (plural: shmoon, also shmoos) is a fictional cartoon creature created by Al Capp (1909–79); the character first appeared in its classic comic strip Li'l Abner on August 31, 1948.
A shmoo is shaped like a plump bowling pin with stubby legs. It has smooth skin, eyebrows and sparse whiskers—but no arms, nose or ears. Its feet are short and round but dextrous, as the shmoo's comic book adventures make clear. It has a rich gamut of facial expressions and often expresses love by exuding hearts over its head. Cartoonist Al Capp ascribed to the shmoo the following curious characteristics. Its satirical intent should be evident:
In a sequence beginning in late August 1948, Li'l Abner discovers the shmoos when he ventures into the forbidden "Valley of the Shmoon" following the mysterious and musical sound they make (from which their name derives). Abner is thrown off a cliff and into the valley below by a primitive "large gal" (as he addresses her), whose job is to guard the valley. (This character is never seen again.) There, against the frantic protestations of a naked, heavily bearded old man who shepherds the shmoos, Abner befriends the strange and charming creatures. "Shmoos," the old man warns, "is the greatest menace to hoomanity th' world has evah known!" "Thass becuz they is so bad, huh?" asks Li'l Abner. "No, stupid", answers the man — and then encapsulates one of life's profound paradoxes: "It's because they's so good!!"
Having discovered their value ("Wif these around, nobody won't nevah havta work no more!!"), Abner leads the shmoos out of the valley — where they become a sensation in Dogpatch and, quickly, the rest of the world. Captains of industry such as J. Roaringham Fatback, the "Pork King", become alarmed as sales of nearly all products decline, and in a series of images reminiscent of the Wall Street Crash of 1929, the "Shmoo Crisis" unfolds. On Fatback's orders, a corrupt exterminator orders out "Shmooicide Squads" to wipe out the shmoos with a variety of firearms, which is depicted in a macabre and comically graphic sequence, with a tearful Li'l Abner misguidedly saluting the supposed "authority" of the extermination squads.
