Plop sour cream and vanilla into your biggest bowl and swirl until smooth.
Carefully fold in Cool Whip with a rubber spatula using gentle swooping motions.
Toss in all your colorful goodies - oranges, pineapple, marshmallows, coconut and cherries.
Give everything just a few gentle turns to combine. Don't overmix!
For best results, tuck it in the fridge for a couple hours before serving.
