Wash and dry the apples thoroughly so the caramel sticks well.
Unwrap the caramels and place them in a microwave-safe bowl with the milk.
Microwave the caramel mixture in 30-second intervals, stirring between each, until fully melted and smooth.
Insert one pretzel stick into the top of each apple to act as a stem.
Dip each apple into the melted caramel, turning to coat evenly, then let excess drip off.
Place the coated apples on a parchment-lined tray to set for a few minutes.
Arrange the apples on a serving board with space between them.
Fill the gaps with piles of candy corn, candy pumpkins, and chocolate-covered raisins to create the pumpkin patch look.
