In a large mixing bowl, combine the drained crushed pineapple, drained mandarin oranges, mini marshmallows, shredded coconut, and chopped pecans or walnuts. Mix well to combine.

Cover the dish with plastic wrap or aluminum foil and place it in the freezer for at least 4 hours or overnight until completely frozen.
