Mudambo, an elephant, has a terrible toothache; all expenses will be paid if the De Sotos will come. Despite their size difference, Mudambo and his wife prove congenial hosts, and the De Sotos bed down for the night on Mrs. Mudambo's pincushion, planning to continue work on the offending tooth in the morning, except that, unfortunately, Honkitonk—a disgruntled monkey- -kidnaps the good dentist at midnight. After a search through the jungle, and the intrepid mouse's escape with minor injuries, the dental work is completed—only this time Mrs. De Soto crafts the repairs, while the doctor directs from his wheelchair. Steig's fresh, humorous turns of phrase, his amiable characterizations, and his gentle colors are as beguiling and ingenuous as ever. The last page hints that the mice will continue to explore "our beautiful planet." (Picture book. 3+)
