Deceptive Spark

From: Lucas Light
Description: Did Father say we need to strengthen the lantern? I think I have an idea. You may not see it, but my eyes can make out a few small holes in the lantern’s body, which energy is escaping through. We’ll need a soldering fish. Can you get it?
Completed: What a wonderful soldering fish! My father forgot about it, but he designed it from my sister Vera’s childhood drawings. This tiny fish can get into the most intricate mechanisms and seal them. It’ll help us keep the lantern from leaking power!
