Darnassus Love Boat
They originate at the northeast side of the dock at, and travel around the lake, eventually returning to the southwest side of the same dock. All of these boats follow the same route.
It is a clickable vehicle, designed for two players to board it. It can be boarded at any point, and can be left through the standard vehicle interface. Once the two players board it, a love heart forms above each of their heads. Upon returning to the dock, the boat despawns, and anyone still in the boat is returned to the dock.
