1Heat oven to 350°F. Line 13x9-inch pan with foil, leaving 1 inch of foil overhanging at 2 opposite sides of pan; spray foil with cooking spray. Make and bake brownie mix as directed on box, using water, oil and eggs. Cool completely, about 1 hour. Refrigerate 1 hour or freeze 30 minutes. Use foil to lift brownies out of pan. Cut into 6 rows by 3 rows. Insert craft stick halfway into 1 end of each brownie.
2Line cookie sheet with waxed paper. In medium microwavable bowl, microwave candy melts uncovered on High 1 to 2 minutes; stir until smooth. Stir in oil until blended. Dip flat back side of each brownie pop in candy; place dipped side up on cookie sheet. Refrigerate 10 minutes or until set.
3Spoon candy coating over remaining sides of brownie to cover completely; let excess drip off. Smooth coating with knife. Immediately attach candy eyeballs. Place 1 licorice piece on opposite sides of each pop to look like neck bolts; refrigerate until set.
4Pipe purple icing on pops to look like hair using small plain tip. Pipe black icing to look like scars and mouth. Let stand until set.
