When I was in Utah, my daughter and I discovered these great salted caramel chips at Smith's. When I got home, I looked for them and finally found them at Fry's. They are the Kroger brand, so look for them at your local Kroger brand store. They are really delicious, you won't believe it.
Then, just like I explain on my tutorial here, http://threewinksdesign.weebly.com/3-winks-writes/do-you-want-to-build-a-cocoa-bomb-the-3-winks-way I molded the green heads. When they were hardened I filled them with the salted caramel chips and about a tsp. and a half of Nestle's Quick.
In order to give the monster hair, I melted some regular chocolate chips and dipped the top of the bombs in it. I thought this would also give the bombs that little extra burst of chocolate.
