Ki and Gil will enter this room through the door at the bottom-right of it. It contains four Blue Bats, one Black Captain Knight (which takes 142 hits to kill and has a yellow visor), nine "Red" Ropers (which are green and take 134 hits) and three "Blue" Ropers (which are yellow and take 254 hits kill).
The key at the bottom-right of the room opens the aforementioned door at the bottom-right of the room, and the key at the top-left of the room opens the door at the top-left of the room. The door up at top-left of the room leads to the last room where the tops of the walls are coloured emerald-green.
The aforementioned door at the bottom-right of the room leads back to Cross Point (Room Pass: SC7), and the door at the top-left of the room leads to Secret Chamber (Room Pass: 23Y). You should remember both of these Room Passes, as both of them may be of some use to you later in game.
