Compies love to stare, and you can take advantage of that. Wait until a compy finds you, and pick it up with a Pteranodon or Argy and into a pen so it doesn't get lost. You need a pen unless you already have 6+ things of raw prime in your inventory. RAW, THEY DON'T EVEN EAT COOKED!!! Kill some brontos and paracers. If that's too much then find some crocs and diplos. Place them in your dino's inventory to slow spoiling, then return to your compy. Punch it or use a club and feed it the prime, and TONS if narcotics or biotoxin. And boom you have a compy. Have fun with this weak but cute shoulder mount.
