Place the green candy melts in a microwave-safe bowl and heat in 30-second bursts, stirring between each, until fully melted and smooth.
Dip the bottom two-thirds of each pretzel rod into the melted candy, letting excess drip back into the bowl.
Lay the coated rods on a parchment-lined baking sheet and press one almond onto the tip of each rod to form a fingernail.
Let the rods sit at room temperature until the candy coating sets.
Combine the shredded cheddar, milk, butter, and garlic powder in a small saucepan over medium-low heat.
Stir steadily until the cheese melts and the mixture turns smooth and creamy.
Transfer the warm dip to a serving bowl and arrange the finished pretzel rods around it.
