Make pudding as directed on box. In food proccesor add cookies and make into fine crumbs. Wipe out containers. Layer starting with cookie crumbs, then cool whip, but about 4-5 worms and allow them to be seen, then pudding and ending with cookie crumbs. Place 4-5 worms stuck in the cookie crumbs. Place top back on and freeze or keep cold in fridge. I def. encourage you to keep in freezer if you transport them any where. I placed them in a cooler with ice packs around them.
