In a large mixing bowl, whisk together the banana cream instant pudding mix and crushed pineapple (juice included) until thickened, about 2-3 minutes.

Add maraschino cherries, diced strawberries, miniature marshmallows, chopped nuts, chocolate chips, and sliced bananas to the pudding mixture, gently stirring until well combined.

Gently fold in half of the whipped topping until fully merged, then add the remaining whipped topping, folding gently to maintain a fluffy texture.

Cover with plastic wrap or a lid and refrigerate for at least 2 hours to allow flavors to meld and salad to firm up.

Before serving, stir gently and garnish with additional chocolate chips, nuts, or cherries, then serve chilled.
