I've taken it to search every room in the house once a character requests for a specific item without stating its location. For example, Eduardo once asked me to find his rubber duckie, but he mentioned leaving it behind in a bathroom that he couldn't remember, so I only needed to check the bathrooms. I got the one where Wilt asked for his scissors too, and I checked every floor started from where he was at the sixth, all the way to Mr. Herriman's office. =__= I was like "WTH's it doing here?!" because Wilt said he'd been wrapping PRESENTS. orz.
Fun times.
