At the bottom of the room, Crystal Flash below a wall pirate to have it walk into Samus. The pirate will randomly walk up and down and wall, but if it sees Samus and jumps across, it will start climbing up the left wall or down the right wall. Without any movement options, it is possible to do this in the left doorframe without any luck, as the pirate just above will start moving down once on screen.
