up until you see a door that is left enter then go right and there will be a purple
lightbulb on the wall hit it and awall that has poking things will get up enter the door
that was where the wall was enter the door when your in go right avoid the enemies climb
the ladder go right and avoid other enemies still go right and a door will be there enter
you will be at the same place of where the purple door is enter it tabuu is there beat him
and you won he is not hard for me i don't know about you but he is easy for me then you
got a trophy when you won the trophy is the ancient minister

austin9blake remember me i am the person who told you how to get darkrai in pokemon
platunim

if you've beaten all the dark characters then just pause and look at the map, see if there
are any portals left you haven't gone through, and go to them, but yeah the place you want
has 2 entry points, one in donkey kong's area, the other i cant remember, i think it was
the very top portal at ice climbers area

but wheres the dk place where i can see tabuu and sonic fighting?
