Mix together Cool Whip and Instant vanilla pudding (do NOT make the pudding, just use it dry). Add un-drained crushed pineapple and both cans of drained Mandarin Oranges. (Use as many mandarins as you like, more/less) Save a few mandarin oranges to decorate the top of the salad. Refrigerate until it thickens again maybe a couple of hours before you need to use it.
