<P> Following the product launch, the General Mills marketing department found that sales performed dramatically better if the composition of the marbits changed periodically . Various features of the marbits were modified to maximize their appeal to young consumers . Over the years, over 40 limited edition features such as Winter Lucky Charms, Olympic - themed Lucky Charms, and Lucky Charms featuring marshmallow landmarks from around the world, were created to drive consumer demands . In focus groups and market research, more brightly colored charms resulted in better sales than did dull or pastel colors . Currently, General Mills conducts "concept - ideation" studies on Lucky Charms . </P> <P> The first boxes of Lucky Charms cereal contained marshmallows in the shapes of pink hearts, yellow moons, orange stars, and green clovers . The lineup has changed occasionally, beginning with the introduction of blue diamonds in 1975, followed by purple horseshoes in 1983, red balloons in 1989, green trees 1991, rainbows in 1992, blue moons 1995, leprechaun hats in 1997 (temporarily replaced the green clovers), orange shooting stars and around the world charms in 1998 (added blue, green, yellow, purple, and red in 2011), a crystal ball in 2001, and an hourglass in 2008 . In 2013, 6 new rainbow swirl moons and 2 new rainbow charms were introduced . From the original four marshmallows, the permanent roster as of 2013 includes eight marshmallows . </P> <P> Older marshmallows were phased out periodically . The first shapes to disappear were the yellow moons and blue diamonds, replaced by yellow / orange pots of gold and blue moons respectively in 1994 . In 2006, the assortment included purple horseshoes; red balloons; blue crescent - moons; orange and white shooting stars; yellow and orange pots of gold; pink, yellow, and blue rainbows; two - tone green leprechaun hats; pink hearts (the one shape to survive since the beginning); with the most recent addition being the return of the clovers in 2004 . The hourglass shape was retired in spring 2018 and was replaced by a unicorn, which was chosen on social media by way of emojis . The size and brightness of the marshmallows changed in 2004 . </P> <P> Recent changes to the marshmallows include the star shape taking on a "shooting star" design, the orange five - pointed star being complemented by a white "trail ." In late 2005, another marshmallow shape was added, the "Hidden Key". It is a solid yellow marshmallow that resembles an arched door (similar to the shape of a tombstone; flat at the bottom, flat sides with a round top). When liquid is added to the cereal, the sugar in the marshmallow dissolves and the shape of a skeleton key appears "as if by magic ." The tagline was, "Unlock the door with milk!" This "new" marshmallow type has been used in other hot and cold cereals, but with mixed success (from characters "hidden" inside a bigger marshmallow to letters appearing). In early June 2006, General Mills introduced Magic Mirror marshmallows . In 2008, yellow and orange hourglass marshmallows were introduced with the marketing tagline of, "The Hourglass Charm has the power to Stop Time * Speed Up Time * Reverse Time". As of 2011, swirled marshmallows and rainbow - colored stars have been introduced . In 2018, for the first time in ten years Lucky Charms retired a marshmallow, which was the hourglass, and added a new permanent marshmallow, the Magical Unicorn . It's powers are unknown . </P>
