dude in the library says go find the buffasaur horn so i figure id go out of the town to that river... nothing? i go every where... the only thing i can accses is my town the city and the gate. whats going on?

You have to leave town and go east into the desert. The Aquaducts should be unlocked. If not, talk to the lilty and the clavat who are standing in town at the pool of water talking about how much the water stinks. That should unlock the Aquaducts. The Buffasaur is the boss at the end of that dungeon.

Yes but how do you get to him? I keep getting stuck after clearing the first area and the gate in front of the jar that you can't pick up opens that leads back to the first area. Can somebody please help?
