Do you hear it? That strange noise that comes out of The Nautilus. Use this stethoscope, and you'll hear it. I've been working here for 10 years, and I've never heard anything like this. Can you find out what exactly happened?

Go to the harbor outside The Nautilus and walk towards East to find the observatory tower. You'll find Bart, there, and I have a hunch that he might have felt something. Please check and see if he's okay.

Maybe you don't hear that strange noise. Place your ear next to The Nautilus. Come on, just try it.

What? Baine noticed that, too?

I mean, I noticed something a few days back, too. Wait... there should be a document that contains the record of activities that day...the log...
