Ben made fake Hidden Immunity Idol that wasn’t shown
Since being voted off, Ben has revealed that he made a fake Immunity Idol which was found by Shambo and not shown on the show.
I made a fake immunity idol. It was really awesome. I killed a chicken with my bare hands and I took its wings and made this necklace that has this big seashell that Russell found — he and I were in it together — and put it back where the original one was.
In other interviews, he said that the idol was found by Shambo but outed inadvertently by Ashley.
