The Return of Ishtar/Slave Pen


 * Ki and Gil enter this room through the first door at the top of it. It contains six Green Vampires (which take ten hits to kill), six Black Vampires (which take twenty hits to kill) and one Blue Knight (which takes thirteen hits to kill and has red eyes; ironically, it debuts after the Blue Captain Knights do).
 * This room wraps around horizontally - and if you proceed in either direction you will end up back where you started. The second and third mazes of Pac-Mania, which was released in the following year and also used a Yamaha YM-2151 FM sound chip for its songs, also wrap around horizontally.
 * The first key at the bottom of the room opens up the aforementioned first door at the top of the room, and the second key at the bottom of the room opens the second door at the top of the room. There are no keys for the other two doors at the top of the room (even though five of them are shown in the image to the right; this is to indicate the fact that the room wraps around horizontally), so there is no way of knowing which rooms they lead to.
 * The aforementioned first door at the top of the room leads back to Banquet Area (Room Pass: 7CY), and the second door up at the top of the room leads off to Kitchen (Room Pass: DCY).
