I use a large foil pan (lasagna size) to both mix and serve. Thoroughly stir together the Cool Whip and sour cream. Add the drained Mandarin oranges and UNdrained pineapple. Mix together. (It will be very watery, but the marshmallows will absorb all of the extra juices.) Add the coconut and mix. Finally add the marshmallows and mix. Cover and refrigerate for a couple of hours before serving, but you can serve it sooner.
