Arm #1: Move to the right side and attack the arm along the way. Find the
switch that is surrounded with a spiky railing up ahead. Pull the switch to
make a secret area under the floor below the arm open up. Attack the arm and
make it fall down into the secret area if it revives then fall down in it
yourself and open the --RED CHEST-- inside. The arm will remain stunned only
for a short while so open the chest quickly. Attack the arm again to stun it
then run back to the switch that opened this door. Pull the switch to make the
doors of the secret area close and trap the arm inside. Grab the handle of the
device to the side and keep pulling it until a small blue light on the side of
the platform below lights up. This will keep the device locked into place at
that portion.

Arm #2: Once the second arm is reached, attack it then quickly grab onto the
large thread to the left of it and climb it. Hop onto the hanging platform to
the side of the thread and pull the switch on the platform to make the blade
hanging on the thread up above fall down and impale the hand of the arm (the
arm must be stunned). Jump off of the platform and grab the device then pull
it to the next blue light to lock it into place once again.

Arm #3: Attack the arm that is further to the right then quickly grab the
device and pull it past the stunned arm. Just in case the hand slaps you there
is another blue light portion that will lock it into place near the arm. Pull
the device up under the set of hanging hands (make sure there are two hand) on
the right side past the arm. Step on the little pressure plate in the middle
of the device and this will connect a spear to the device. Run back to the
left and attack the arm then push the device over to the locked position in
front of the arm. The arm will revive yet again even as the device is locked
into place, but attack the arm once more time and the hand of the arm will get
stuck in the spear as the arm is thrown up and the spear will fall and pin the
hand to the floor.
