well if you ever watched the dragon ball gt series uub is a guy that makes a fusion with
fat buu and you will need him to get dragon arena

you van get uub wain you fanash kid buu wath sbirt baob and you go to world tournament in
map

to unlock uub finish off kid buu with spirit bomb and then go to the arena

uub is buu backwards because uub is another of buu's forms just a good form instead of
evil
