Traces of the Stranger

Exploration Stage: Scientist's Mansion
From: Rayden Storke
Description: Director Black has always suspected Mr. Albert Wise, but he may not really be involved in Mr. Zaenti's disappearance, right? There is a somewhat familiar object that has fallen under the cabinet...can you help me get it?
Completed: This looks like a battery for a stun gun! Batteries for such weapons are not available in regular stores and can only be made by a gang of avocados. They must have broken into Mr. Zaenti's house with the weapon!
