Okay my mom told me that in grade 10 she learned about this tribe that lived near greece that were nicknamed the blueberry men, but when i search blueberry men, nothing about them shows up. now, the big reason there were called blueberry men was because they used blueberry dye to stain all of their skin, making them look purple, anybody know the name of these people. Another thing is that they arent around anymore, this was a very long time ago.
