Place the softened cream cheese, shredded cheddar, chopped chives, garlic powder, and salt in a mixing bowl. Stir until the mixture is evenly combined and smooth.
Lay a sheet of plastic wrap on the counter. Scoop the cheese mixture onto the wrap and form it into a round ball. Gently press the sides to create ridges that resemble a pumpkin.
Sprinkle the paprika over the entire surface and roll the ball lightly so the coating sticks evenly.
Insert the pretzel stick into the top center to act as the stem. Wrap the cheese ball again and chill it for at least 30 minutes to firm up.
Unwrap and place the cheese ball on a serving plate with the assorted crackers arranged around it.
