In a large bowl, combine the cream cheese, gouda, cheddar, garlic powder, Worcestershire sauce, salt, and pepper. Mix well until smooth and evenly blended.
Shape the mixture into 26 small balls, then gently press each one to create a slightly oval shape.
Roll each cheese ball in the crushed cheese snacks until fully coated.
Using a toothpick, lightly score vertical lines around each cheese ball to create a pumpkin-like texture.
Insert a small piece of green pepper on top as the stem.
Serve immediately or refrigerate until ready to serve.
