Plants vs Zombies was released by PopCap Games in 2009, with music composed by Laura Shigihara. The roof is the final area of Adventure mode, played in daytime across the top of the house, and its theme is part of the wider soundtrack that fans associate with the original game rather than later sequels. Clips and loops of the stage music spread through gameplay videos, remixes and fan projects on YouTube and gaming forums, keeping the roof theme familiar long after players finished the campaign.
