When word gets out that the happy lion has saved a rabbit from a hunter, his home at the zoo becomes a haven for all the rabbits in the area, and when that becomes so crowded that the guests begin to fall into the moat, the townspeople are persuaded to adopt all but the original one and his wife as pets. A disappointingly tame episode even for so domesticated a creature as the happy lion, and it doesn't help that the pages are jumping with rabbits which could just as well be long-eared dogs and goats and deer.
