Properties and Uses
Chungite being used as a Chungus delicacy has always been controversial, although the health benefits are immense, as they grant massive amounts of hugeness. This use of Chungite has always been reserved for the very wealthy. Big Chungus was rumoured to have consumed some Chungite, which contributed to his massive size, although this has not been confirmed by the devs.

Chungite has often times been used to power Chungusland, being a very efficient power source and allowing the Chungi to grow bigger by absorbing its power. In this use, it's been very encouraged by the Chungi's culture. Chungus like to sniff farts and piss in bottles.
