rusty heart

Exploration Stage: Clock Tower
From: Vera
Description: Yenco's heart lost some much-needed fog, but that's not the only problem. It seems that the mechanism inside has not been lubricated for a long time. No wonder it's broken! The lubricant Jenko uses in his watches is called pearl oil. Can you bring it to me?
Completed: Thanks for bringing the pearl oil. It is in this tower for a reason. The special feature of this oil is that it will not harm any living creature thanks to its organic composition. In other words, if you put it on Jenko's heart as a lubricant, he will not be affected by the toxicity.
