Push a toothpic through the base of the colt coral with a little bit of flesh below it so it won't rip through. Use a rubber band to attach each end of the toothpick by wrapping it around the rock you would like to attach it to. Be sure you only loosely wrap the rubber bands or the toothpick will pull through the flesh. Wait at least a week before removing the bands and toothpick. Be careful when removing the toothpick to not pull the colt off of its new home. Good luck.
