Add instant vanilla pudding and milk in a mixing bowl and whisk well until smooth and creamy.
Refrigerate instant pudding mixture for 10 minutes to thicken up.
Meanwhile, remove Oreo creamy centers from cookies and add chocolate Oreo cookies to the food processor and process until you have fine crumbs. If you do not have a food processor, put in a baggie and smash with the bottom of a glass or rolling pin.
Remove any large chunks of cookie that might be left and re-process until all of the cookies are fine crumbs or you could clog your piping bag.
Remove Vanilla pudding from the refrigerator and add processed Oreo crumbs, thawed whipped topping and Instant Chocolate Dry pudding mix.
Use a spatula to gently fold ingredients together until mixed.
Spoon The Grey Stuff Mixture into a piping bag fitted with a star tip.
Place in fridge for 15 minutes to chill.
Pipe dessert mixture into small serving bowls and top with sprinkles or sugar pearls.
Serve immediately (with tasting spoons or on top of sugar cookies) or refrigerate, covered, until ready to serve.
