Spider Demon Imp is a zombie and a boss in Journey to the West in Plants vs. Zombies: All Stars. It attacks plants by shooting spider webs from its spider machine to a plant, dealing damage to it. Different with other zombies, it can also use its special skill when it is not a mini-boss, which is shooting a big spider web that will then land onto all plants, dealing damage to all of them. When it is a boss, it has eight stages of health and takes four turns to activate its boss skill, which is the same as its normal form, but with higher damage.
- This and Spider Devil Zombie are the only zombies who are based on spiders.
- Both are also based on the Spider Demons from the novel Journey to the West.
