I made these for my sons boy scout Halloween party. I used chocolate marshmellows to make the rice krispie mixture brown (to look like dirt). The kids loved them. I used six cups of rice krispies instead of five.

These are wayyyy too cute! I made them for my son's Halloween-themed birthday party. A word to the wise... be careful when mixing in the worms. We learned to let the mixture sit and cool slightly so the worms don't melt and mix in.
