The Return of Ishtar/Water Duct


 * Ki and Gil will enter this room through the door at the top-left of it. It contains two "Blue" Super Ropers (which are yellow), four Yellow Oozes, four Pink Oozes, four Dark Yellow Oozes, four Dark Green Oozes and one Land Urchin (which will immediately invalidate Gil's energy fraction contact).
 * The key at the top-left of the room opens the aforementioned door at the top-left of the room, and the key at the bottom-right of the room opens up the door at the bottom-right of the room. The aforementioned door at the top-left of the room leads back to Secret Staircase (Room Pass: Q32 - it's same as Library) - and the door at the bottom-right of the room leads all the way back to Water Line (Room Pass: YF7). Therefore, in retrospective, using the "Password Game Continue" option on the start screen in order to reach Under the Moat would not have been such a good idea, after all...
 * NOTE: If Ki or Gil walks over the exact centre of the top-right of the room, another trap door will open up beneath them, and the text "A CHUTE!" will appear on the screen (for the second time if either of them found the first one in Forbidden Hall), and they will then be warped to Entrant Hall. This is also the last of the three secret warps in the game - as the first one was in the aforementioned Forbidden Hall, and the second one was in Third Cell.
