I "made this up" last nite and it came out delicious. Use any fruit and pudding you like.
1 can of mandarin oranges- refrigerated and not drained
1 can of tropical fruit- refrigerated and not drained
frozen strawberries or other fruit
1 box of instant banana pudding
Whisk together fruit and pudding in large bowl till dissolved. Stir in desired amount of marshmellows and Cool Whip. Will thicken overnite in ref.
