A mystery is afoot. You could even say a mystery is popping. And, of course, "Once you pop, that's great!" — at least, according to Prongles, the mystery chip brand appearing in Target stores across the U.S. Luckily our trusty internet sleuths are at the top of their game, and have uncovered some eye-popping (OK, I'm done) details that suggest Prongles may be connected to Cards Against Humanity. Bustle has reached out to Cards Against Humanity and Prongles for comment, but has not yet heard back.
