Sand Canal is a dungeon in Wild Arms 3.
Wild Arms 3[]
Its easy to find; take your horse northwest up the span of cliffs to the co-ordinates X: 4123 Y: 10942. It's hard to miss; there's a large narrow land mass that looks like it's "reaching" over to the other side. When the land fails and you need to get to the other side of a body of water, you build a canal, right? Before entering, save your game, because your enemies have beaten you to the canal and are waiting for you.
As soon as you enter the Sand Canal, you'll catch something creepy and green out of the corner of your eye. Proceed a little further, and you'll find the reason why I told you to save your game prior to entering the canal.
