Green Wilma

There's something decidedly odd about Wilma: at breakfast, her parents are startled by their offspring's request to ``Pass the bugs''; later, she shocks her teacher by snagging a ``tasty little fly'' with her long pink tongue. Most noticeably, however, Wilma's skin has turned a deep, froggy green, a fact that her polka-dot T-shirt and beribboned blond hair cannot conceal. In this strange and gleeful story, it's surprisingly easy being green--the extraordinary heroine is the envy of her elementary-school class. Arnold's rhyming text is as buoyant as his leaf-colored, rubbery-limbed protagonist; his roly-poly, bug-eyed characters perfectly suit the story's quirky theme and manic action. Squiggly, threadlike lines--suggestive of handmade paper--cover every surface in the richly colored illustrations, subtly adding an unusual softness and depth. Though some youngsters may be puzzled by the book's conclusion, this gifted picture book creator ( No Jumping on the Bed! ; The Signpainter's Assistant ) has taken his talents in a quirky, unconventional direction with this tale, which takes daydreaming to new and zany heights. Ages 4-8. A Children's BOMC selection. (Mar.)
