They should at least have a warning that that much food coloring in anything can make one's .... urm.... output colorful too. I used to do novelty birthday cakes for people, I'd warn them that the cookie monster cake will make a frosting monster kid (or adult for that matter) poop blue for a day or so.

At least they aren't red. I have become allergic to whatever red they use in things like red velvet anything.
