In a bowl, mix together the cream cheese, sour cream, mozzarella, parmesan, and sun-dried tomatoes. Form the mixture into a ball, wrap with plastic wrap, and chill for an hour.
Meanwhile, in a small bowl, mix together the breadcrumbs, oregano, paprika, and red pepper flakes. Once the cheeseball has set, roll it in the bread crumb mixture to evenly coat.
(To make your cheeseball resemble a pumpkin, add a real or faux pumpkin stem to the top. Then use the tip of a chopstick or the back of a butter knife to create grooves.)
Serve with thin, crisp breadsticks and crackers.
