There's something I don't get. I've located 6 of the dragonballs but when..

If you want to get that one go to the botom part south of chi chi and gokus house with vegita and go down a bit then west and you will go to a different area and you will see a snake kill it or run past it and you will see a level 30 vegita sighn there hit it and go through and you will see a capsle get it and go forward you will see some ninjas look on your dragon radar and you should be okay for the rest of the trip ps when you reach a fortres type thing hit the box thing to get in level 35 goku and you will see 3 dragon head with water comeing out of there mouths, there will be a north, west and east way go to the north and go left hit a switch next to a save point next go past the ninja and robot (left) and go to the left way and there will be another switch, hit it and the dragon heads in the north of the ninja and robot I just told you about will go red and you will have to hit it go south of the ninja and robot and go left and north amd there will be a dragon head past the ninja and robot again hit it the same for the west side hit the dragon heads in order west east and north the water will be gone from the watering dragon heads and go through the house door a wile later general tow (tue) will be there with a man and defeat him and you will get the dragon ball, use this because your not getting a shorter hint! And it took me 10 mins to type!.

OK, first, when you get to east district 439, go to the woods and go west. Keep going to the left and you will see a barrier for vegeta. Once you break it and go inside, you need to find the lake with 3 statues of lions with water pouring out of their mouths. You need to go find the three castles with a lion statue inside each one. There is 1 castle with switches on each side of it. Push the switches. Go into all of the castles and push the buttons in the lions mouths. They should go from red to green. This will make the water in the lake go down. When the lake has dried up, go inside the cave. You will have to use Son Goku to defeat Gen. Tao and get the dragonball from him. Good Luck!

Trust me if your saying to long to read then read it because it will get you the dragonball 80% =)

You got to open the vegita gate located in one of the screens below goku's house then break the gate for goku. Once you are in the castle, go around
The pond and go to the north. You'll come in an area where you can go to the
North, the west and the east. Go to the East and the West. You'll see two
Pumps. Press the A Button when you are standing in front of them. Now you have
To turn on three other statues. The first is located to the north of the
Screen where you could go East or West to the pumps. Now go back to the room
With the pond and go to the East to disable the second statue and then to the
West to disable the third. Now go to the pond where the water is gone and go
Down to pick up the Four Star Dragon Ball. You'll have to fight general Tao after this
