Firstbridge

"'A bridge over the beautiful waters that flow from the waterfall. Low-level monsters sometimes appear.'"

About
Firstbridge can be discovered by speaking to the MILF in Firsttown and selecting "YES" when asked about slaying monsters. Afterward, the location will become accessible on the World Map when The Adventurer moves over the tile depicting a bridge.

The area consists of a bridge spanning the water from a nearby waterfall, and is adjoined by a small forest area. As described by Sukumizu it is a good place for beginners since it is full of low-level monsters. Sukumizu herself will sometimes appear on the section of the map containing the bridge to provide insight and store items.

The Red Mushrooms which grow here are poisonous, and contact with them will afflict The Adventurer with a poison status. Atop the land to the left of the waterfall is a tile containing a Yellow "Recovery Mushroom" which can fully restore The Adventurer's HP.

Behind the waterfall itself is a damp and slimy cavern known as a Rockit House. This hidden room contains three ordinary Rockits and a singular Big Rockit which serves as a hidden boss. Upon its defeat three chests will appear. On re-entry to this room without leaving the overall dungeon, four Rockits will appear in the cavern. The frequency of Rockits in this dungeon make it an excellent place to acquire Pervy Liquid with minimal risk.
