Bumbunga comes from the native language Parnpangka, which means rain lake. The iron sheet is molded along the way, giant cockroaches, mice, tin men, flying saucers, big flies, etc. This is a very ironic group of dead plastic made by civil environmentalists to protest the government's construction of landfills in the area. Among them, the big squall is also standing next to the Australian Channel 9 certification of the "world's largest squall"!
