In any contest for all-around unoriginality, this might be a contender. Wally is allergic to fur and feathers, and determined to have a pet. He and his folks find frogs too active and too noisy; frumpish busybody Aunt Beulah mistakes snake Sheila, hibernating in the refrigerator, for a sausage (so good-bye snake); but a hermit crab seems harmless. . . and, indeed, after an obligatory mix-up changing shells, hermit crab Harold wins a prize as Most Unusual Pet in the local show. The story is harmless too, but awfully hackneyed.
