In a large bowl, combine melted chocolate and whipped topping; mix well.
Reserve 1/4 cup crushed cookies. Stir remaining 1-1/4 cups crushed cookies into chocolate mixture. Spoon into pie crust and sprinkle reserved cookie crumbs evenly over top.
Cover loosely and chill at least 2 hours before serving.
NOTE: Why not have fun with this and garnish it with mini mint sprigs, placed in rows to represent the beginnings of a garden, and a few gummy worms for color?
