Line a baking sheet with parchment paper and set it aside.

Place the white candy melts and vegetable oil in a microwave-safe bowl. Heat in 30-second intervals, stirring between each, until fully melted and smooth.

Dip each pretzel rod into the melted white candy, leaving about two inches uncovered at one end to create the bone shape. Let excess coating drip back into the bowl.

Place the coated rods on the prepared baking sheet and allow them to set at room temperature for 15 minutes.

Melt the dark chocolate chips in a small bowl using the microwave in short bursts. Spoon the melted chocolate into a piping bag or zip-top bag with a tiny corner snipped off.

Pipe short lines and small dots on the white coating to resemble bone joints and knuckles. Let the chocolate set before serving.
