Baer "content and motifs point to an African origin for this tale."
Clarke has Liberian parallel. In Mossi tale, Rabbit's suitor tasks are: milking buffalo, getting leopard skin, and tusk of elephant.
This tale and also Chase069 appear in Bascom's African Folktales in America series. Bascom observes there is no ATU type for "trickster seeks endowments" and "to achieve his goal, trickster must obtain one or more things."
Baer: "These two Uncle Remus tales reflect the most common goals found in Africa: in this tale, Rabbit is trying to win a girl; and in the next he seeks confirmation of his wisdom and cunning."
