After a breakneck descent, we stumbled upon another terrifying sign. According to Robot, the giant mushroom must have flown here from the Mushroom Forest, 35 kilometres away. Only a Physics storm could have hurled it that far.

There was no entrance to the Thought-pipe in the mountains. The onward trek to the City of Scientists led only across the parched grassland and through the Gardens of the Mushroom and Black Forests.
