In a large mixing bowl, combine the vanilla pudding mix with the well-drained crushed pineapple. Stir vigorously for 1-2 minutes until thickened.

Gently fold in the whipped topping (Cool Whip) using a spatula.

Add the marshmallows, shredded coconut, chopped nuts, and shredded carrots one at a time, folding gently each time.

Transfer the mixture into a serving bowl and cover it tightly with plastic wrap. Refrigerate for at least 2-3 hours.

Before serving, sprinkle extra coconut on top for garnish and serve cold.
