Zones are magical areas within the UnUniverse that can only be accessed through portals. These portals are created by powerful guys, and they are used to lock up enemies. Zones are very dangerous, as they can give Seizures, make your ears explode, and they have a power level of OVER 9000.
The first recorded sighting of a zone was when Patrick Star accidentally opened one while eating a Krabby Patty. With his new power, he banished Squidward Tentacles to the Patrick Zone for three years. Since then, many other guys have utilized the awesome power of zones.
