Dragon Head became available during the Spring Cleaning 2008 event and later the Clean Up Britannia 2011 event for 50,000 turn in points. This House Addon can either be placed in either an eastern or southern facing.
It cannot be crafted using a Taxidermy Kit in the way of other trophies.
There is a very rare white Dragon Head. It is currently worth millions, while the "red" one is not.
