I don’t think it’s Briar Rabbit. It’s Br’er (Brother) Rabbit. FWIW.

Brer Rabbit, trickster figure originating in African folklore and transmitted by African slaves to the New World, where it acquired attributes of similar native American tricksters (see trickster tale); Brer, or Brother, Rabbit was popularized in the United States in the stories of Joel Chandler Harris (1848–1908). The character’s adventures embody an idea considered to be a universal creation among oppressed peoples—that a small, weak, but ingenious force can overcome a larger, stronger, but dull-witted power. Brer Rabbit continually outsmarts his bigger animal associates, Brer Fox, Brer Wolf, and Brer Bear.
