stereotypical broken English. He dresses more like a somewhat stereotyped Indian than a caveman, and at one point even specifically states that he is an American Indian. He and A.D. were not frequently seen after Peter returned from his epic journey. The two are the most oft-appearing non-regular human characters in the history of the strip other than the Guru, due to the strip's tight focus on its core cast of humans. His name is a spoof of the name Pocahontas. Peter's Pen Pal, An unseen person whom Peter corresponds with by tossing "floating stone tablet" letters into the ocean and receiving answers at a later time. Setting The characters live, for the most part, in caves, in what appears to be a barren, mountainous desert by an unidentified sea. Background detail is often limited to a simple horizon line broken up by the occasional silhouettes of a stray volcano or cloud. "Retail stores", "shop counters", and "businesses" are symbolized by a single boulder, labeled (for instance): "Wheel Repair", "Advice Column", "Psychiatrist", etc. The February 5, 2012, strip gives a nearby location of N 53° 24' 17" W 6° 12' 3", which is in present-day Dublin, Ireland.

B.C., like Hart's Wizard of Id, is a period burlesque with a deliberately broad, non literal time frame. As time went on, the strip began to mine humor from having the characters make explicit references to modern-day current events, inventions, and celebrities. Increasingly familiar visual devices, like the makeshift "telephone" built into a tree trunk, also started to blur the comic's supposed prehistoric setting and make it rife with intentional anachronisms.
