Place the softened cream cheese, shredded cheddar, parsley, chives, garlic powder, and 1/2 tsp paprika in a mixing bowl. Stir until the ingredients are evenly combined and the mixture holds together.
Scoop the mixture onto a sheet of plastic wrap. Use your hands to shape it into a smooth round ball.
Sprinkle the extra paprika over the ball and roll it gently until the surface is fully coated for the pumpkin color.
Set the ball on a serving plate. Push the pretzel stick straight into the top center to form the stem.
Arrange the crackers around the cheese ball and serve.
