Take the ice cream out of the freezer and let thaw until it's just a bit stiffer than soft serve.
In the bowl of a food processor, combine the pretzels, graham crackers and sugar. Pulse until fine crumbs and then add melted butter.
Press the crumbs into the bottom of desired baking dish. Set in the freezer while you make your filling.
Spread the softened ice cream into an even layer on top of the graham cracker crust. Return to the freezer.
Meanwhile, combine all of the ingredients for the frozen yogurt topping. Spread in an even layer on top of the ice cream layer.
Freeze for at least 4 hours or overnight.
When you are ready to serve, allow to thaw for about 10-15 minutes.
Garnish with fresh fruit.
