This is the Jungle of the Kokoto region from the original Monster Hunter game of the 1st Generation on the PS2. Due to the very dense vegetation in most areas the range of vision is restricted which makes it harder to spot and keep track of monsters roaming in the area. There are expansive underground cave systems in areas 4, 9, and 10 filled with ankle-high water, in which the Khezu happily resides in. The area has plentiful amounts of different mushrooms to be gathered and is a good source of Village Points from the Special mushrooms. A quite large river runs through areas 3 and 7 can have Plesioths swimming inside. In Monster Hunter Freedom Unite the Nargacuga and Emerald Congalala can be fought here for the first time. Hot drinks are needed for the 3 caves which contain Vespoids, Hornetaurs and Great Thunderbugs to make gathering or fighting monsters harder for the Hunter/s.
There are animal effects in area 5 in MHFU, standing here long enough snakes will slither across the floor, and birds fly over head. these 'effects' cannot be killed.
