It seems like something is bother Zen, so check out the new Stroll that appears and you find out that he saw a butterfly stuck in the spider's web in the northwest room of the eighth floor of the Clock Tower. If you attempted to go straight there and free the butterfly, you'd have to fight the Capturer FOE first. Should you happen to want to do that, be prepared that it knows Stone Mist, Mahamaon and Mamudoon. It is weak to electricity and only nulls Poison, so you can use any other ailment or bind on it.
However, if you want to free the butterfly without fighting the FOE, you'll have to go up to the ninth floor and move the piston in the northwest corner down to the 8th floor. Just make sure to be careful the Reaper in the room nearby when getting to the piston and remember that leaving the labyrinth will reset the piston.
