In the LocoRoco stage, World 3 - Level 8, this is the location where you can find and unlock Budzi and it is also Budzi's favorite zone and his habitat.
Dolangomeri has a dark grey-colored ground with spooky stuff in there such as dark trees. It is the darkest and scariest area of the LocoRoco Planet. Because of it's environment, the Mojas settle in their invasions in that place. It is ironically as well as the natural habitat of Budzi.
