The once-solid-but-now-swirled-green shake features reduced fat vanilla ice cream blended with green mint-flavored syrup, topped with whipped cream and a maraschino cherry.
Prices are the same as your local McDonald's regular shake prices ($1.89 to $2.79 in my area).
The shake are available for a limited time only.
