CRUMBS: Preheat oven to 350*F. In food processor, process wafers into fine crumbs; then add coconut and pecans. Pour the melted butter over the wafer crumbs mixture and toss until well blended. Spread crumb mixture onto cookie sheet and bake for 7-12 minutes or until golden brown, tossing mixture lightly a few times. Cool completely before filling.
PUDDING:In a large mixing bowl, whisk together the vanilla pudding and milk with a whisk until well blended. Fold in the whipped topping. Place pudding mixture into a resealable plastic bag, snipping a small tip from a corner to pipe into glasses.
ASSEMBLY:In your serving glasses, layer crumb mixture, pudding, chopped topping mixture, toffee bits, and chopped banana. Serve immediately.
