Franken Berry, the Beloved Halloween Cereal, Was Once Medically Found to Cause Pink Poop | Food & Think| Smithsonian.
Another interesting Halloween story from Smithsonian. I dimly remember something about this growing up. I thought it was kind-of cool. I mean really? Pink poop? Sounds pretty cool to most kids I think. Parents panic, but what the heck. Maybe that was part of the fun of the whole experience?
PS- they even managed to find videos of the original commercials 😉
