Prepare the dip: Place the caramel dip into a small bowl and position it near the centre of a large serving board.
Add the larger ingredients: Arrange the popcorn, pretzels, crackers, cheese and grapes around the dip, spreading them across different sections of the board.
Make the mandarin pumpkins: Peel the mandarins and insert a small piece of celery into the top of each one to create a pumpkin stem. Arrange them around the board.
Add the ghost marshmallows: Place the ghost marshmallows around the board, spacing them between the larger ingredients so they stand out.
Add the sweet treats: Arrange the chocolate-coated candies, gummy worms, chocolate sandwich cookies, mini peanut butter cups and mini chocolate chip cookies around the board.
Add the fresh fruit: Place the strawberries and remaining grapes into any larger gaps, keeping wet fruit away from crackers where possible.
Fill the gaps: Sprinkle candy corn and candy eyeballs into the smaller spaces throughout the board to create a full and colourful appearance.
Decorate: Add plastic spiders, mini pumpkins or autumn leaves around the outside of the board. Keep non-food decorations separate from the food.
Serve: Serve immediately for the best texture. If preparing ahead, cover and refrigerate for up to 4 hours, then add the popcorn and other crunchy snacks just before serving.
