Black chinchompas are very widely used for quickly leveling up Ranged, and players will make most of their money from Hunter by catching them.
Upon arrival, it would be a good idea to kill one to see where it respawns so that traps can be set accordingly to surround the spot. Kill any chinchompa that wanders off and quickly reset the traps if necessary. All in all, on average, around 300 chinchompas can be caught per hour with minimal interference from PKers.
