Poison swamp nooooo

We all know that Miyazaki loves his poison swamps, the sicko. When Eurogamer asked him if the DLC will include poison swamps, this was his response:
In a word, yes. But this was actually a point of introspection for me after creating the base game. It was only after creating it that I realised I really like to create poisoned swamps. And this was a little place of introspection and reflection for me. So maybe, when players reach the poisoned swamp in the DLC, they will feel a little bit of this retrospection.
I don’t know about you, but that certainly looks like a poisoned swamp to me. I’m gonna hate this place!
