Plants vs. Zombies is a tower defence game first released by PopCap Games in 2009, in which players place plants to stop waves of zombies approaching their house. Hit sounds like this one are part of its everyday combat audio, heard whenever a plant attack connects with an enemy. As clips from the game were shared on soundboards and in short gameplay videos, the short, recognisable impacts became handy meme material. They still appear in edits today because the game remains widely remembered and its cartoon sound design reads instantly, even without any visuals.
