Chen's Camp was Chen's temporary base in the New Ninjago City subway tunnels. After his army was transformed into fake Anacondrai, Chen and his forces traveled to Ninjago and took refuge in the subway system, where they set up a series of tents and planned their attack on the city. It was here that Chen realized the transformation spell was wearing off, and that in order to preserve it, they would need the essence of a real Anacondrai. Kapau and Chope set off to capture Pythor, the last living Anacondrai.
After Pythor was taken from Kryptarium Prison and brought to the camp, Chen threw him and a swamp rat on a spinning wheel, and the rat began chasing him. As such, Pythor began sweating, and the fake Anacondrai used his sweat to sustain their transformed selves. Afterwards, Chen led his army into Ninjago to wreak havoc on the city.
