From Creatures Wikia
The perfect metaroom for your Toxic Norns and Plague Ettins, the Garbage Dump consists of 2 levels - the bottom level contains several peculiar objects, including a strange organic recycler. A pond, filled with green muck, is guarded by a gate to keep curious norns from drowning.
It overlaps with the Monturarrium. This overlapping will be fixed with Monturarrium's new release.
