**Mix the Cheese Base:** In a mixing bowl, combine the softened cream cheese, shredded cheddar cheese, ranch seasoning, garlic powder, and smoked paprika (if using). Mix thoroughly until well combined.
**Shape into a Ball:** Transfer the cheese mixture onto a sheet of plastic wrap. Use the wrap to shape it into a round ball. Twist the plastic wrap tightly around the ball to hold its shape, then refrigerate for at least 2 hours or until firm.
**Create the Pumpkin Look:** Once the cheese ball is firm, remove the plastic wrap. Roll the cheese ball in the finely crushed cheddar cheese crackers until evenly coated. Use a small knife or toothpick to create vertical lines around the cheese ball to mimic the ridges of a pumpkin.
**Add the Stem:** Insert a pretzel rod or celery stick into the top center of the cheese ball to resemble a pumpkin stem. Garnish with parsley leaves, if desired.
**Serve:** Place the cheese ball on a serving platter surrounded by crackers, veggies, or pretzels, and serve chilled.
