The City Cesspool was featured in the episodes Walk for Your Lives and Dibship Rising. It is the city's repository for both sewage and trash alike, and any living thing that is unfortunate enough to fall into its murky depths will have their innards "melt for millions of years". In Dibship Rising, when Dib climbed into Tak's Ship, he was bound with mechanical tentacles and the ship started to run toward the City Cesspool. It is then revealed that Zim was making an attempt on Dib's life by controlling the ship from the back.
