The Nether Boogaloo!!

A ghost that lurks in the depths of the nether known as the Boogaloo!  This ghost only becomes aggresive if you are holding or wearing anything made of gold.  The Boogaloo will attempt to take the gold by force.  They have a lot of health and do a lot of damage.  They can also fly and turn invisible.  Boogaloos can only attack you if you are very close to them.  When they are killed they can drop gold nuggets.
