In a companion to Pigs from A to Z (1986), ten piglets, inspired by a bedtime story, set out on an elaborate fantasy adventure to find ``a lost place with huge stone configurations.'' Shot by a cannon, an anchored rope becomes the basis for a bridge; the pigs also, with some remarkable engineering, drill through a mountain before finding ten mysterious stone images of Arabic numerals in a secluded valley. As before, Geisert's intricately detailed etchings are carefully designed, with all the numbers—and pigs—to be found (with some difficulty) on each spread and with a key to the numerals (not the sometimes elusive pigs) at the end.
