Prepare the Pineapple: Drain the can of crushed pineapple, pressing out as much juice as possible to avoid making the fluff too watery.
Make the Pudding Base: In a large bowl, whisk together the instant vanilla pudding mix and sour cream until combined.
Add Pineapple: Stir in the drained pineapple. Make sure the pineapple is well mixed into the pudding mixture.
Add Whipped Topping: Gently fold in the whipped topping until everything is well combined.
Add Coconut and Marshmallows: Stir in the shredded coconut and mini marshmallows (if using). If you want extra crunch, add the chopped nuts as well.
Chill: Cover and refrigerate for at least 2 hours to allow the flavors to meld and the texture to set.
Serve: Serve chilled as a dessert or side dish at your next gathering.
