March 7 (UPI) -- Cookie-lovers enjoying the newest variety of Oreos -- marshmallow Peeps flavor -- noted some unusual side effects: pink tongues and pink poop.
Twitter users who sampled the Oreos, which came out shortly before Monday's National Oreo Cookie Day, reported first that the Peeps-flavored cream inside the sandwich cookies turned their tongues pink, then later discovered the coloration wasn't limited to their mouths.
