Your next bowl of Lucky Charms will be missing one of their iconic marshmallows! 

Since 2008, the yellow hourglass marshmallow has been included in every box, but come this spring, it will officially be retired.

The company has not yet revealed what will replace the hourglass. 

The following shapes have all been sent to the Lucky Charms graveyard: blue diamond (‘75), purple horseshoe (’83), swirled whale (’86), red balloon (’89), rainbow (’92), pot of gold (’94) and shooting star (’98).
