yup, chocolate worms. a few years ago i bought 2 chocolate bars, one for my mom and one for me. my mother opened her's first and noticed the dust that was on the wrapper moving. i opened mine and there was the same thing. after a heated phone call with 4 different supervisors we put the bars (wrapper and all) into a ziplock bag and mailed it to the distributor. they mailed us back 2 bookletts worth 50$, and a written appology from the plant manager. i guess if the bars sit long enugh or if air can get in the bugs will grow.
