Thaw the Cool Whip.

Drain the pineapple and oranges (use the juice in place of part of the water if desired).

Bring the water to a rolling boil and add all the Jello. 

Stir constantly and cook for 2 minutes. 

Remove from the heat and pour into a bowl to cool -stir occasionally to hasten the cooling process.

Add the thawed Cool Whip, oranges and pineapple.

Fold until well blended and serve.

I place all the Jello mix powders into a small bowl while the water is heating and then whisk them into the boiling water. 

I cut the orange sections into smaller pieces and occasionally I use crushed pineapple instead of the tidbits.

Any flavor of Jello can be used in this recipe to suit the season, for example, I use orange at Halloween,  red for Valentine's Day,  green for St Patrick's Day.
