"The City Sewers stink. Most people just avoid this world for fear of disease, but this crazy Sewer Cleaner actually gives up all of his free time to try and clean up the place.
The Sewer Cleaner needs your help. There are 30 different missions for you, each harder than the last. He will ask you to collect some items that you can only find around this world. Bring them back to him and he will reward you for helping to clean up. If you fail to complete the mission level within the time limit, you will fail and go back to level one."
This mission requires you to find items such as Poop and Bugs. If you try to do the Sewage and Trash Heap dailies, you would mostly get MP instead. Bugs can be found in the Crevice, which requires Traps (the better ones are expensive).
