  Hello,
  
  The most unusual skull I’ve ever seen is the one belonging to the muntjac deer. If you don’t know what it looks like, take a look on Google Images!
  
  Muntjac deer have a gland on the side of their eyes, which makes a liquid that is very stinky! Male muntjac deer produce this from their eyes to mark their territory, and to attract muntjac deer. If you look at muntjac deer skulls on Google Images, you will see where the massive gland is that produces this liquid!
