IGN: xX_Hackerz_Xx Bug: I saw a bug where someone posted where you could hit Jerry and Harry's heads and I was trying to see if any other head was like that, then I found that if you hit the chest head it turns all greyish Proof: Before: http://prntscr.com/2d4njs After: http://prntscr.com/2d4nw5
Isn't a bug. Player Heads are based off Skeleton Heads. So, once you break it, it looks like a skeleton head, but after that, it returns to the normal head.
No, it seems when players do this, it stays gray, yesterday I saw someone punch a head, I looked at it and it was grey, when I went to change it back to a chest (which is simple, you just punch it again) nothing happened D:
