Talk to him and then you will have a battle. Once you have done this,
walk up to the POSTER and press the switch. Now turn right and go
down the steps. Now go right and go down another set of steps. Once
you have done this, go down and left and up again until you reach
another set of steps which you may go down. Here, travel left until you
can go down. Turn left at the first turn, and then where you can next
go down, there are some arrows pointing left and right. Go on the ones
facing left. Then go down and then once you have stopped spinning, go
left and down. Don't tread on any more of the arrows, then go left and
down, and then walk on the arrows nearest to you, the ones that are
one square in front of the ones below you. You will now be spinning right
and then down. Once you have stopped, go down then go right, and then
go up. Go down the stairs and then go up. Turn left and there will be a
man here, from TEAM ROCKET.
