Hey Fetter,
Eden's Crush is an artificially constructed girls pop group. It is the "result" of a TV mini-series called "The Making of Pop Stars" (or something like that). Like many bands today, it was sponsored and developed by corporate interests. They were just much more blatant about it with Eden's Crush. "Maybe if we do it right before their eyes, they won't notice...."
But as far as tickling goes, I guess, who cares? They are attractive, sexy, and, apparently, ticklish!
Hope this helps.
