Nursery Land characters, both human and animal, coexist in this goofy 1940s spoof of classic film noir detective stories for grown-up kids. When her triplets disappear, Mrs. Pig hires detective Jack B. Nimble. Jack and his klutzy secretary Miss Muffet suspect B. B. Wolf. Characters from Humpty Dumpty and Henny Penny to Jack and Mrs. Sprat become involved in the investigation before Jack finds the missing boys and earns a dubious award: a kiss from a pig.
