Cut the processed cheese into 4 equal pieces.

Peel and cut the pumpkin into bite-sized pieces. Microwave in a heatproof container covered with plastic wrap at 600W for 3 minutes. Mash until smooth and mix with powdered cheese. Divide into 8 portions.

Place the mashed pumpkin mixture on plastic wrap, add a piece of processed cheese in the center, and wrap to form a ball. Repeat with black olives in the center, making 4 balls each for a total of 8.
