The latest cream flavor to come out of something called "the Oreo Wonder Vault" has consumers wondering why their poop suddenly looks like it could've come from a unicorn. Two weeks ago, Oreo released a limited edition of its cookie with a vanilla shell and a filling flavored like the love-it-or-hate-it marshmallow candy Peeps, reports USA Today.
One reviewer claims the filling is the same one used in the Marshmallow Crispy Oreos, but with one major difference: It's bright pink and appears to turn your mouth—and even your dung—bright pink, too. "My spit looks like Pepto-Bismol" hours after eating the cookies, one Twitter user complains, per Delish. Adds another, "My roommate ate a whole pack of Oreo Peeps and left a pink stain in the toilet."
