YUMMM!! I'm in!! Wendy's is launching a new frosty flavor on November 15th and it's going to be Peppermint! The new Frosty will be a combination of peppermint syrup mixed into a vanilla Frosty base and will replace the Strawberry Frosty. If you LOVE the Frosty and want to help out a great cause, you can buy a $2 Key Tag to benefit the Dave Thomas Foundation for Adoption and receive a free Jr. Frosty with every purchase for the entire year.
