While the two women set about with the pyre, Roga walks over to the dead crab and fishes it out of the spot in the lagoon where it sunk.  Then he walks over to the campfire and carefully fishes a narrow stick out of it.  After sticking the stick into the sand to extinguish it, Roga then carefully wedges it into the crab's mouth.  Then he sits down and patiently holds the crab over the fire while it cooks.<br/><br/>(If I need to make a check, I rolled a 4.  I don't know what to add to or subtract from that.)
