Place the softened cream cheese, shredded cheddar cheese, paprika, garlic powder, and onion powder in a mixing bowl. Stir until the mixture is smooth and evenly combined.

Lay a piece of plastic wrap on the counter. Scrape the cheese mixture onto the wrap and shape it into a round ball with your hands.

Use the edge of a spatula or a butter knife to press shallow vertical lines around the ball to create pumpkin segments.

Cut the top off the green bell pepper and trim a short stem piece. Press the stem gently into the top center of the cheese ball.

Transfer the finished cheese ball to a serving plate. Arrange the crackers and vegetable sticks around the base.
