Line 2 baking trays with grease proof or baking paper. Place 6 of the skewers or sticks equally spread out on each baking tray.
Place each colour of candy melt into separate microwave safe bowls and melt one of them following package instructions. Keep a close eye on them to make sure that they don't burn – they melt very quickly!
Once melted, spoon the melts into a disposable piping bag or small plastic freezer bag.
Snip the corner off, then pipe in a random squiggly pattern over one of the skewers. Repeat with 3 more skewers or until all the mixture has been used up.
Working quickly, push an assortment of large and small candy eyeballs into each pop to turn them into monsters.
Repeat with the other two colours of candy melts until you have 12 monster pops.
Once finished, place the trays of monster pops in the fridge to harden and set – about 15 to 20 minutes should be enough.
Remove from the fridge and store in a cool dry place until ready to serve.
