Combine the cheeses and pumpkin in a stand mixer fitted with the paddle attachment.
Mix on medium speed until well combined.
Add the herbs, salt and pepper and mix again until combined.
Transfer the cheese mixture onto a large piece of plastic wrap and shape into a ball as best you can. Wrap up the cheese and place in the refrigerator for at least 30 minutes.
Remove from refrigerator and reshape into a ball again. Now that the cheeses are hardened a bit it should be easier to shape.
Place the pumpkin seeds and extra herbs on a plate. Roll the ball of cheese in the mixture and gently press down so that the seeds and herbs stick to the outside of the cheese ball.
Keep wrapped in plastic and refrigerated until serving.
