"Theyre always after me Lucky Charms!" A favorite for more than four decades, delicious Lucky Charms cereal features frosted oats and colored marshmallows. Lucky the Leprechaun creates the marshmallow shapes - hearts, moons, stars, clovers, horseshoes, pots of gold, rainbows and red balloons - with his rainbow magic. While kids love the taste, parents are happy that Lucky Charms is fortified with 12 vitamins and minerals, and is a good source of calcium. Its magically delicious!
