Drizzle 2 tablespoons chocolate sauce into a 9-inch graham cracker crust. Fill with scoops of ice cream (vanilla, chocolate and strawberry) and freeze until firm, 1 to 2 hours. Beat 1 cup heavy cream, 1 teaspoon vanilla and 2 tablespoons each confectioners' sugar and the syrup from a jar of maraschino cherries with a mixer until stiff peaks form. Top the ice cream with 2 sliced bananas, the whipped cream and more chocolate sauce. Top with walnuts and a cherry.
