Plants vs Zombies 2 launched in 2013 as the mobile sequel to PopCap's tower-defense hit, sending players back through time to defend their lawns with new plants against new zombie types. Its bright main theme became closely linked with the series, and short clips of it later spread through gaming edits, reaction videos and soundboards, where the tune works as instant shorthand for a goofy garden battle. Players still recognise it years later because the melody is so tied to the game's playful, cartoon style.
