It was floor 7, you ignored what Dandy has been trying to offer you (Useless stuff). Before the elevator opened, you can hear the song 'clair de lune' playing in the distance, with odd footsteps. You stepped out of the elevator, and saw in the distance, the same innocent flower you kept seeing trying to offer you stuff, now a giant being that's nearly the same size as the whole map. You went to go extract ichor. After you were done, Dandy heard the machine being completed, and then started to chase after you after he saw you.
