Ultra Divine Water
is a special rare magical drink that can increase your power by a great deal. However the drink is made up of painful poison so the chance of surviving the power up process is very slim. About a million to one.
The location of the Ultra Divine Water is a top guarded secret. (And not found anyway on this cache page) Only those who are actively seeking the Dragon Balls have a chance to find it. Somewhere along the way as you attempt to get all the puzzle pieces to find the 3 star Dragon Ball you will either come across the coords to find the Divine water. If you know the manga story, you'll understand when you'll get the water. Once you get the coords for the Ultra Divine Water you'll be about 20 meters from the cache. A former World Boxing Champion from Okinawa will show you the way. The cache is magnetic located behind that boxing champion.
However for the lucky cacher who just happens to be in the right place this former world boxing champion from Okinawa will show you where it is.: 
If you just so happen to see this picture the cache hidden right behind him.
When and if you get your hands on this water, you'll get a puzzle piece to find a dragon ball. Good luck!
