When the stork delivers a crop of lambs, one of the ewes is left out. But there is a lion cub who is named Lambert. He was apparently mismarked. So he is inadvertently given to the mother. She decide to keep him and chases the stork away. Of course, the lion cub is rejected by the others, not recognizing his being for what it is. The conclusion is predictable. Still, it is well worth seeing and the song is very memorable.
