8 ounces each blue, green and red candy coating disks
30 pretzel rods
Blue, green and red colored sugar
6 ounces each white and black candy coating disks
30 M&M's minis
Place each color of candy melts into separate microwave-safe bowls. Working with 1 color at a time, heat in microwave, stirring every 30 seconds until smooth. Dip 10 pretzel rods in each blue, green and red melted candy coating, stopping 2 inches from end; allow excess to drip off. Immediately roll in matching colored sugar. Let stand on a parchment-lined pan until set. Reheat candy coating as needed.
Adding 1 teaspoon at a time, stir melted black candy coating into the white until desired shade of gray is achieved; reserve remaining melted black candy coating. Dip the uncoated end of the pretzel rods into melted gray candy coating for handle; allow excess to drip off. Return to parchment-lined pan until set.
Place reserved melted black candy coating into a piping bag fitted with a small round tip; pipe 3 lines onto handle. For power buttons, secure M&M's minis to handles with melted black candy coating. Allow to set completely before serving. Store at room temperature in an airtight container between layers of waxed paper.
