Make Pops. Working with one bag at a time, cut a small opening in decorating bag. Pipe a circle, about 2 in. in diameter, on a parchment-paper covered cake board. Rotate about 1 in. of the treat stick into the candy. Tap to even out candy. Scatter sprinkle mix over candy. Add candy eyeballs. Repeat for remaining desired number of pops.
Chill pops until set, about 5 to 10 minutes.
