To make your own you'll need:
A bag of pretzel rods
A package of almond bark
A microwave safe bowl
The smallest bag of almond slices that your grocery store sells
The inspiration used green colored candy melts. The comments discussed peoples' problems dyeing white chocolate with liquid food coloring. I opted for almond bark and made a test batch for the coloring just in case. The almond bark is artificial enough that it doesn't seize up or get thick when using liquid dye. I melted half the big block (six cubes at once) and used 3 drops of green and one drop of red (so it looked a bit more brown instead of pastel). I would have liked to try going even greener, but I didn't want to risk it. If you do use white chocolate, you could probably dye the chocolate with paste dye without having problems with it seizing up.
After figuring out the dye, dripping/dipping on the chocolate was easy enough. I smoothed out the excess with the back of a spoon and put the almond slices on the tips immediately after I put them on wax paper to set. I couldn't get the knuckles drawn on the way that the inspiration did. It didn't work at all right after it had been dipped, and when I waited until it had set up a bit, all I could manage was a sloppy line with a butter knife...so the knuckles are a bit crude.
I think they turned out pretty cute for my first poke at them--and no matter what, they taste great. I hope you all have a great Halloween!
