Dark City

A new area added in the Birmingham Knights DLC and contains the The Joker non player character and the Yellow Pikman upgrade
it is very smelly and smells like New Jersey
many stinky enemies can be found throughout the biome which makes it very stink centrific
there is a portion of the level called the big tree which will attempt to steal the beheaded's belongings by bumping into it which the Jonkler will help you avoid with his jonklets
