Begin by peeling the navel oranges and sectioning them into bite-sized pieces. Cut away the white pith and set aside in a mixing bowl.
Open the can of pineapple tidbits, and pour both the tidbits and the juice into the bowl with the oranges.
Add 1 cup of flaked coconut to the mixing bowl, allowing it to absorb some pineapple juice.
Sprinkle 1/4 cup of powdered sugar over the fruit mixture to enhance sweetness.
Using a spatula, gently fold all the ingredients together without mashing the fruit.
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to let flavors meld.
