This is an environment protect project, which is inspired by fatberg in London. 

All the fat, wet wipes and something else flush down the sewer gather together to make up fatberg, which cause the block of sewer. In the story, the fatberg is turned into a baby character who grows up bigger and bigger feeding on things on the sewer. People tried to solve the problem. However, it is like a circle. The same problem happens again like a loop.
