2007 champion Lyndal Morgan received a custom mini-helmet to commemorate his 2007 OIL Bowl championship. His Whackers beat his arch-rival (Leal's Norman Nobodies) to conclude the second season of the OIL. 
The 2014 champion Dirty Hippies helmet is still a work-in-progress because it is more complicated. We're starting with the 2014 champion and then going back to the beginning of the OIL to work our way back to 2013.
