I actually did this to a hitch hiker fugia I have - its green with an orange mouth. It was on a side of an orange hammer, about the size of a dime. I pulled it off and placed it on the sandbed. in a few months it grew to 3 inches, and there was another dime size one on the hammer again. I have pulled them off about 4 times and so far a new one keeps growing back from where I pulled. I even broke one in half when i pulled it off and gave it to Ben, 2 months ago. Its a full circle now and much bigger.
