Heidi is the wife of Bombhead's biological father George Baker. Bombhead had been conceived during a fling between George and Sandra Burke in 1984. Sandra had died in July 2004 and Bombhead began a search to find his biological father, with George revealing himself in November 2005 (having had a chance encounter with Bombhead months earlier). George introduced Heidi to Bombhead in November 2005. Merely days later, Bombhead attended George and Heidi's peculiar wedding before deciding to join them in the circus - despite his fear of clowns.
