Wash the 3 green apples thoroughly under cool running water. Once clean, carefully quarter the apples and remove the cores and seeds. Create a whimsical v-shape cut into the center of each apple quarter for the monster's mouth.

Spread a thin layer of creamy peanut butter evenly into each monster mouth on the apple quarters, ensuring that the peanut butter fills the v-shape cut.

Press the 2 tablespoons of pumpkin or sunflower seeds into the edges of each monster mouth to form teeth.

Cut triangular pieces from the 2 ounces of sliced cheddar or Colby jack cheese and place them into each monster's mouth.

Dab a small amount of peanut butter onto the back of each candy eye and place them atop the apple slices.

Arrange the assembled Green Apple Monsters on a platter or serving dish and serve immediately.
