You take the staircase to the right of the balcony and walk down it, coming to the level of Nakii's brain. There's a path that was completely hidden by the balcony that leads to a tunnel opening some 20 or 40 feet away. The path is alongside Nakii's brain and you can't help but touch the brain. It was amazingly soft. Once you've made it to the "tunnel" entrance, you see the massive brain stem that holds up the brain. The tunnel goes on past the brain stem and into what looks to be an ordinary subway station. Nakii's spinal cord was as thick as a redwood tree trunk and the "Nakii-Metro" was sitting right on top of it. The "Nakii-Metro" was half the size of a real subway car. You get on board the Nakii-Metro--which looks to be made out of both bone and flesh--via a short staircase.
Inside the Nakii-Metro, there is some kind of control panel. On the panel, it shows you the "stations" where you can get off and explore. Currently, the Nakii-Metro is at the "Brain"....while the next station takes you close to the massive eyes of Nakii. There are at least twenty other stations, all leading to the various parts of Nakii's body. The very last "station" is actually inside the tail of Nakii which is marked as "Balance control". Near the middle of the spinal cord is a "station" marked with "Milk Production". As a mammal, you knew that Nakii produces milk but you thought it odd that it should be marked that way. You shake your head and make your selection with the dial-like device that controls the Nakii-Metro. You're going to stop at the eyes first, and then make your way down from there. The Nakii-Metro springs to life and starts to move.
The trip doesn't take all that long; 4 minutes at the most. When the Nakii-Metro stops, you get off and head for another tunnel opening. On the ceiling of the tunnel there's bundles of wires that must be nerves that go from the eyes to the brain of Nakii. The tunnel is 40 feet high and perhaps 60 feet wide. The tunnel gets slightly narrower as you go on, but still big enough for you to walk comfortably in. When you've walked about a mile, you come to a huge vaulted chamber. On one wall of the chamber is the IMAX version of Whale-Vision. You walk into the chamber, only to discover that you can't pass a certain point; a thin membrane stops you. On the other side of the membrane is what looks like water.
The IMAX Whale-Vision is showing some sort of underwater canyon that's incredibly deep.
"That's the Marianas Trench as you humans call it" said Nakii in you head.
"That's on the other side of the world" you blurt out.
"Well, I'm a fast swimmer" laughs Nakii. "we marine animals simply call it 'The Deep Valley'"
"Wait...how do you know the names..." you trail off, remembering that Nakii could read you mind. You continue to look for a handful of minutes before you spot something in the ocean. It's a submarine not far from Nakii. Nakii keeps her distance from the submarine.
"Is that one of ours?" you wonder out loud.
"I don't know, nor do I care" said Nakii. "I usually ignore those things"
