When the Cat in the Hat came back, he brought an alphabet’s worth of Little Cats and more rhyming mischief. Now his creator, the late Theodor Geisel (better known as Dr. Seuss), is making a return of his own, with more scheming felines, panicked goldfish, and something called a “Zinniga-Zanniga” in tow. Seven rarely-seen Seuss tales are collected in The Bippolo Seed and Other Lost Stories, which will be published this September by Random House. The stories originally appeared in Redbook magazine in 1950 and 1951 but never made it to book form. They were tracked down by Seuss expert Charles D. Cohen, whose list of credentials—collector, scholar, dentist—is straight out of of one of the master’s fantastic tales and who has written an introduction to the book. The title story involves a sly cat, a sucker of a duck, and a bad decision, while “Gustav the Goldfish” is an early, rhymed version of A Fish Out of Water, a book by Helen Palmer, Geisel’s wife. Readers will also encounter the twin twosome of “Tadd and Todd,” a band of hungry creatures who follow a boy home in hopes of “Steak for Supper,” and “The Strange Shirt Spot,” the source for the bathtub-ring scene in, you guessed it, The Cat in the Hat Comes Back.
