In a whimsical parody of Moore's ""A Visit from St. Nicholas,"" Mom narrates; the six kids are eating junk food and watching three TVs when eight red-capped cows come down the chimney to sing carols and bring presents--baseball equipment for an all-night game between cows and family. There are plenty of amusing details here, both in the spritely verse and in the mock- earnest pictures of the placid bovines and of a home furnished in ""cute"" souvenir-shop decor. Not essential, but pleasingly silly.
