Android # 16
is an strong android created by the evil genius, Dr. Gero. This android has a inbuilt directive to kill Songoku on sight. However he has a gentle nature loving character and gets upset when someone destroys nature or kills animals.
Right now he is very angry will the huge amount of construction going on in the Yomitan area that has destroyed a once lush quite peaceful spot. So you must find him and reason with him to get a puzzle piece to find a dragon ball.
The cache is hidden very close to stage one of an old archived cache called "nuts about Okinawa" So finders of that cache have the advantage. As mentioned above there is a huge construction project going on in the area but if you start from the waypoint you can find your way to GZ but using several farmer roads. You may meet a few farmers on the way and I got here on bicycle and all the farmers greeted me with a friendly smile. I'm not so sure if they would be as friendly if you come down the roads in a big car so please be considerate and walk or ride.
update: To find the cache start at the north end of the bridge (now incomplete) You will need a little climb/bush bash up the bank to the roots of a tree. Look for a UPR here.
