Line a baking sheet with parchment paper and set it aside.
Place the white chocolate melts in a microwave-safe bowl and heat in 30-second intervals, stirring between each, until fully melted and smooth.
Dip each pretzel rod halfway into the melted white chocolate, letting excess drip back into the bowl.
Lay the dipped pretzels on the prepared baking sheet and immediately press two candy eyes onto the white chocolate while it is still soft.
Melt the dark chocolate melts in a separate bowl using the same method, then drizzle it lightly over the coated pretzels with a spoon.
Sprinkle the Halloween sprinkles over the pretzels before the chocolate sets. Let everything harden at room temperature.
