You can choose from Red's Birdberry which is a yummy assortment of berries which taste great! Or Piggies Sour Apple Sorbet which wow its both green and sour if your a sour lover like I am you will LOVE it! It also leaves you with a green tongue : ) The special flavors come in a special cup, in celebration of Angry Birds.
Gluten free? TCBY has a huge assortment of Soft Serve which is gluten free so all can enjoy. You can find these and many other fun flavors at your local TCBY. I like to take my kids to enjoy a frozen yogurt at our local TCBY you can find yours here.
