Kellogs has an Apple Jacks cereal that turns milk, "Slime green." It still has the apple flavor but makes your milk look like slime, basically. This is disgusting and kind of genius. Folks are used to their milk turning chocolatey, but green is always a weird little gimmick. This isn't the first time a cereal has intentionally turned milk green, but doing it in a way that makes us think of slime is creative, in a kind of nasty way. I saw it at the store but didn't buy it as I was in a rush. I might get it the next time I see it due to my curiosity about weird things.
