Outhouse Zombie is a Farm Zombie in Plants vs. Zombies 3, which you can first encounter at Floor 15 of Devour Tower. She is encased in an outhouse, which serves as armor. When it is destroyed, a stink wave is released and goes down the lane, stunning all plants it hits.
She shares her name with a spawnable zombie in Plants vs. Zombies: Garden Warfare, Plants vs. Zombies: Garden Warfare 2, and Plants vs. Zombies: Battle for Neighborville. However, her appearance is drastically different, as her outhouse is now wooden.
