Stuff you’ll need for this method:

Exceptional kibble

A couple stone foundations

10-20 cannonballs

A cannon

A pteranodon set to passive

Pteranodon saddle

So, place a stone foundation and put a cannon facing an open area you’ll be able to lure the rock golem to, find a rock golem on your pteranodon and lure it in front of the cannon, leave the bird floating in the air just out of the golems reach and it will just stand there as you get off and shoot it with the cannon until it’s out.
