Being left alone at work has it advantages of course, and one of them is that you'll be able to sneak around where you're not really supposed to be. Remember the Dodo Box? Time to open it! Go to the stand where the box is placed and select it. You'll be met with a puzzle. The goal is to get the Dodo past all the predators and to the bottom right corner of the puzzle safely. Move the dodo around with the buttons on the bottom left of your screen. Use the white partitions to safely maneuver around your predators. When you're done with all the three predators, click on the button to open the box and read the letters. (Images below will provide a guide to the Dodo movements and yes, Senior and Junior levels mean a varied game style)
Oh yeah, and reading the letters will clue you in on the fact that Heather has written one of the letters herself. You can confront her about it later. Once you're done with that, pick up the phone and call the zippy line which will in turn let you call Lynn Manrique, the American Historian. She'll talk to you about Noisette and her paramour Hans, which leads Nancy to wonder if Hans was related to Dieter.
