The icy slush drinks also come in Wild Cherry Fanta and Blue Raspberry Fanta drinks. They're currently available the the Wichita area in Kansas as well as Central and Western Kansas locations.
While these would be new for McDonald's in the U.S., McDonald's currently carries frozen slush-type drinks in several countries including Australia, Malaysia, and Thailand.
Closer to home, the chain has occasionally offered similar drinks but of the non-soda variety. These include Frozen Lemonade, Frozen Strawberry Lemonade, and the Cherry Berry Chiller. They also regularly offer coffee-based frappes and fruit-based smoothies.
