A family of anthropomorphic bunnies embark on a fanciful airship voyage to the Moon after the father, feeling unwell, is persuaded to seek a change of air. Their trip, guided by a gray squirrel and piloted by a hawk with an owl lookout, reaches a cold, icy lunar island where they stay in an ice hotel, ride reindeer sleighs, and attend a glittering court at the Moon King's palace. Encounters with giant moon-people, unfamiliar dried foods, and wintry amusements blend gentle humor and imaginative descriptions of travel, wonder, and domestic concerns during an otherworldly holiday.
