The City Center Mall is a shopping mall in the city that Invader Zim takes place in. The mall has over fifty floors, and is guarded by a fanatical security guard known as Sergeant Slab Rankle; he takes his job far too seriously, to the point of having installed lasers around the mall and using Zombies to attack anyone who dares to trespass in the store (however, the zombies are harmless, and do little more than stagger and trip over themselves).
