Oh! You plan to search this old, abandoned laboratory? If so, I'd advise you to buy my purple scarf. Why, you ask? Because there's someone rather savage inside, who will refuse to talk with you if you don't wave this flag. In fact, she's blind as a bat, and she'll believe you're an old acquaintance. Unfortunately, her memory is as bad as her sight, and she'll forget about you a few hours after you leave. Thus I advise you always to find an object of this kind before talking to her, because otherwise she'll ignore you completely.
