Mix pineapple, grapes, apple, strawberries, cherries, peach, pear, and coconut together in a large bowl. Stir in vanilla extract and enough sour cream to coat fruit mixture. Gently fold marshmallows, banana, and kiwi into fruit salad; top with pecans.
For a holiday twist, add dried cranberries and ground cinnamon or ginger.
The shredded coconut can be toasted for a nutty flavor.
