In a large mixing bowl, beat together cream cheese, Velveeta, shredded cheese, garlic powder and Worcestershire sauce until completely blended.

Using plastic wrap, shape the cheese mixture into a ball. Wrap the cheese ball in plastic wrap. Then, use the stem of a paintbrush or pencil to create the vertical lines of a pumpkin. Refrigerate until ready to serve.

Remove the plastic wrap and roll the cheese ball in crushed Cheetos, coating the entire cheese bal. If needed, remove the excess crumbs from the pumpkin lines or press deeper lines into the cheese ball.

Transfer to a serving plate and press the bell pepper stem into the top of the cheese ball.
Serve with crackers or vegetable dippers.
