I just sent this letter to General Mills:
I would like to know if your company ever intends to produce a 'marshmallows only' version of Lucky Charms. I enjoy Lucky Charms very much, but the non-marshmallow bits have declared war on deliciousness. Even if you do not currently plan to create a marshmallows-only version of Lucky Charms, please consider it. I do not have nearly enough condensed sugar in my life.
It started out totally serious, but then it turned into a satire on how insanely unhealthy my stupid idea is.
I'd still totally buy it, though.
