Majin Buu
is a powerful being and is the final villain in the Dragon Ball Story. Although Buu is very strong, he is very childish and loves to eat chocolates, candies and other sweets all the time. Although Majin Buu does a lot of evil things for Babidi, he doesn't realise it is bad. Eventually the Fat Buu turns out good when a skinny evil buu emerges from him. (See the cache Super Buu for that)
For this cache Majin Buu has been sitting on top of a mountain doing silly bad things. The cache is located on the highest peak (Shioyafuji peak) in this mountain range. This particular peak does not have any views due to the surrounding tree cover. Nevertheless the hike to get here is really nice and you can see many things the beautiful nature of Okinawa has to offer. There are three approaches to get to this cache. (see the trailhead waypoints) Each waypoint has parking and there is a cache or the start of a multi cache near each trailhead. So if you want to get them all in one trip plan carefully to avoid backtracking. Once you find the Fat Majin Buu you will get a puzzle piece to find a Dragon ball.
Good Luck! and enjoy the hike!
