BEAT milk and pudding mixes in large bowl with whisk 2 min. Gently stir in half each of the COOL WHIP and cookie crumbs.
SPOON 1 Tbsp. of the remaining crumbs into each of 15 cups; top 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.
