Line a large baking sheet with parchment paper.
Melt the green candy melts with the coconut oil in a heatproof bowl set over simmering water (or in 30-second microwave bursts), stirring until completely smooth.
Dip each pretzel rod fully into the green candy, turning to coat, letting the excess drip back into the bowl. Lay on the parchment.
While the coating is still wet, press one almond onto the top tip of each rod, pointed end facing out, as the "fingernail."
Dip a toothpick in the melted black candy melts and draw 2–3 short knuckle lines across each finger.
Chill 10 minutes until set. Serve on a Halloween platter!
