That "eating healthy" thing everybody says people should do? You remember that? This is not your giveaway then.

Lucky Charms are “magically delicious,“ but you’ll have to be magically lucky to win one of 10 limited-edition, marshmallows-only boxes of the cereal that General Mills is giving away in a new contest.

“A box of marshmallow-only Lucky Charms has always been the unicorn of the cereal world--fantasized about, but never seen,“ General Mills wrote on its blog this week.

To enter the contest, “just share a photo of yourself holding an imaginary box of Lucky Charms on Facebook, Twitter or Instagram between October 14 and 18 using [the hashtag] #Lucky10Sweepstakes.“

The company also released a helpful instructional video starring Biz Markie explaining the giveaway. Biz Markie! Sung to the tune of that one song of his everybody knows!
