Wash and slice fruit in the manner you would for a traditional fruit salad. If it is off-season for certain fruits, add some sugar for sweetness (you can also use a sugar substitute). Toss fruit together in bowl. Refrigerate.
Mix softened cream cheese with equal amounts of fluff marshmallow creme; mix until smooth. You can leave it white or use food coloring to compliment your choice of fruits. Put in bowl and refrigerate until you serve.
You can serve it as a dip or serve dessert shells filled with dip and topped with the fruit.
