heres how i got mine. put six stone pillars down. three on each side. put one more between them than put down a large bear trap. lead it into the pen. once trapped in bear trap run around and place the final stone pillar behind it. shoot it with tranqs and than knock it out. give it your choice of food. give it bio toxin to keep it unconceous. i got my level 14 doing this. follow this strategy and he or she is yours!
