Well, so we made it into the elevator. It's not very clean in here anyways, so take some dust
from the huge flowerpot and pour it all over the place. A fast and tidy cleanobot comes along and sucks in all the
dust. But we are even faster than him, so pick him up while he is in front of you. After shaking the sucker for a
while he will drop a lightbulb
. There is no other place for the lightbulb than in the upper right corner on the
elevator panel. So we just found the first bulb for the elevator.
Now we can go upstairs, but we don't know the right combination yet. The leaf of the plant is in
the way so step under it and expand your robot to reach up for it. Pull down the leaf and you can see the pentagram beeing the symbol for
the top floor. Use the panel and enter the pentagram as the destination. We will go up in no time.
