As the popularity of freestyle skateboarding declined, Mullen was urged to transform his style to join the street skating trend that was becoming increasingly popular at that time; however, Mullen was very reluctant due to a fear of compromising his integrity, whereby the foundation of his skateboarding would be "sold out". Such pressure is alluded to in the World Industries video, "Rubbish Heap", in which Mullen's sequence ends with team member, Jeremy Klein, deliberately breaking his freestyle skateboard (which is also the first recorded focus of a skateboard) and then handing him a note from Rocco, accompanied by a street skateboard deck, in which the end of freestyle is declared.
