General Mills is welcoming a new limited-edition gold coin marshmallow to select boxes of Lucky Charms in honor of Lucky the Leprechaun’s birthday, which just happens to fall on St. Patrick’s Day.

The new gold coin marshmallow can be found in limited-edition green boxes of either Original Lucky Charms or Chocolate Lucky Charms, through March 2020.

Both varieties feature a special, limited-edition marshmallow blend featuring pots of gold, green shamrocks and the new gold coins. Additionally, the special boxes also feature a Leprechaun Trap design on the back so families can try to catch the elusive Lucky the Leprechaun at home.

You can find the new limited-edition Lucky Charms in the cereal aisle at retailers nationwide for a suggested price of $2.50 (10.5-oz box), as well as in 19.3-oz and 21.2-oz boxes for $3.33 each.
