BEAT milk and pudding mixes in large bowl with whisk 2 min. Stir in 1-1/2 cups Cool Whip and 1/2 of the cookie crumbs.
SPOON 1 Tbsp. of the remaining crumbs into each of 14 (7-oz.) plastic cups. Cover with layers of pudding mixture and remaining crumbs.
DROP remaining Cool Whip by spoonfuls onto desserts to resemble ghosts. Add chocolate chips for the eyes.
