Bring water to a boil, then add the 3 boxes of jello puddings.
Stir constantly until mixture starts to thicken. Pour into serving bowl; let set overnight.
Just before serving, add 12 ounces Cool Whip and 1 bag frozen rasberries partly thawed.
Stir together.
Notes
(Variations can include using orange jello and mandarin oranges, strawberry jello using strawberries, or blueberry jello using blueberries, just whatever you tend to like.)
