This droll collection of updated animals is a distant cousin quite removed from the bestiaries of the past. Modern species exclusively, they reflect Anne Folsom's hawk-eyed view of the human zoo. There is the Lesser, or Watergate, Tapir, domesticated by Halde Man and Ehrlich Man who Worshipped ""an oracle who spoke through the oval orifice""; the Hippypotamus, whose bare essentials include ""a small plot of grass and a quadraphonic stereo system""; the Opec, or Wolf in Sheik's Clothing, who took stock of his resources and then took everybody's stock, resources, banks, and airlines; and the Junk Mole, definitely third class, who was born in a mailbox and leaves small prints wherever he goes. Most of these creations are witty word plays slyly extended: the Duck-Billed Platitude, the D.A. Aardvark, the Hieronymus Vache, the Utterly Grossbeak--an acquisitive bird who dreams of owning a Cattle Yak. Although a few seem familiar (the Good Housekeeping Seal, the Male Chauvinist Pig), most are fresh and topical. Accompanied by nimble line drawings, they're short and sassy critters--you'll be tempted to add your own.
