It is possible through the use of an LJA and a sidehop to skip Ooccoo who is normally blocking your way at the start of the dungeon. On the way up stand just ahead of the black square shown in the video and LJA slightly left because the trigger is oval shaped. On the way back down stand on the fourth step and sidehop slightly away from Ooccoo you make it past the trigger.
It is possible to skip opening the first gate with the pressure plate with a jump attack. To do this clawshot the target before the gate, the further back you target the easier it will be. Then just press A to drop and B to jump attack. Some people prefer to mash B then press A while others will just time it.
It possible to also skip opening the second gate with both statues on the pressure plates with a well timed roll. To do this you want to kill all Lizalfos first, easiest with a bomb-arrow and the keese although you can do this without killing the keese. Next place a pot or statue on the left pressure plate and stand on the other. Once the gate is fully opened you can time a roll through the gate. Please note you want to walk of the pressure plate then roll, rolling instantly will not make it
A slower but easier way to skip the gate is to use a super jump using the keese behind the gate. First kill the Lizalfos in the room so you don't target them during your B-Charge. Next boomerang the keese behind the gate to you and transform into a wolf at the gate as soon as the boomerang comes back to you. B-Charge on the keese and back away from the gate to the middle of the room, when your B-charge attacks the keese you will Super Jump over the gate
The Fastest Meathod but has tight timing, however with practice getting used to have fast to press B after A it isn't that bad.
Normally to raise the block and to get up you need two statues, one of which is at the bottom of the room which can only be reached by turning the platform in the middle. However due to the fact there is a cutscene the first time you raise the block you can skip getting the one at the bottom making it much faster. Please note if you fail this trick you will have to get the statue statue because the cutscene making thing possible only plays once
1) First place one statue on the left pressure plate
2) Stand on the second pressure plate sideways for about 1-2 seconds
3) Sidehop onto the block and with the right timing it will raise
4) during the cutscene hold forward and mash A, due to analog glitch this will make you sidehop and not jump attack
Normally to get this heart piece you come back here on the way back down with the Dominion Rod and use it to move the statues onto the pressure plates at the end. However using an angle throw on the second from the top step you can throw statues onto the pressure plates and collect the heart piece early, which saves back tracking.
Normally in this room you are required to keep shooting the crystal switch with the bow through the holes in the fence, however you can quite simply skip the last two hits by using the clawshot on the target through the hole
It is possible to get the boss key early on the way up by getting onto the railing. This can be done in three ways. Once you are on the railing you can walk up the railing to the end, line up the hearts as shown in the videos and just hold forward, then you can just clawshot up and spinner around to the door.
1) Using a backslice - Get a slight angle and backslice as shown - Only used in 100%
2) Using a Jump Attack - Stand on the fourth step at the end and line up your first heart slightly to the left of the pillar, then go to the other end of the step and jump attack
3) Using the Boomerang - Stand on the fifth step and target as shown so the boomerang takes longer to get from target to target, this will give you time to LJA
For the barrier in the room with the rolling spikes you don't have to place a statue to keep the barrier down. Just stand on the pressure plate and target high on the stairs, you can then just LJA past the barrier before it comes online again
On the way down for the first bell you can skip placing a statue on the pressure plate. This is done by increasing the distance the Dominion Rod can be used with a backhop
1) Place the statue on the block
2) Stand on the edge of the circle by the pressure plate
3) Use the Dominion Rod and then quickly backhop
4) You should control the statue and the block should be raised
5) Roll into the bell
It is possible to skip the scale puzzle both on the way up and way down. On the way up after doing Boss Key Early simply jump past the scales. On the way down stand very close behind the statue, line yourself up with the other end and backhop across by mashing A. If you fail you will have to do the puzzle normally.
In the big circle room you never have to turn the platform if done right. First of all you can skip going up a level by controlling the statue through the floor, to do this just aim at the wall in the same place at the video. Next you can make the statue fall all the way to the bottom with backhops, remember to wait for the inside spinner to pass so you have time to get the statue to fall. There are two ways to perform the final part, the fast method is shown in the video where you jump and bonk against the wall, this makes the statue come outside the middle so you can instantly go to the Bell. The other method is to lose control of the statue, jump down and control from there to get it out of the middle
For the poe in the circle room it is possible to gain control of link during his animation of collecting the poe and even transform before wolf link holds the soul up. To do this make the backflip from the finishing blow land on the switch, you can then move and transform before you hold up the soul.
The fastest movement through this room is to gain control of the small statue after the rolling spikes at an angle so you can roll past it but get the statue stuck on the wall. Once you pass over the black square on the floor (about 3 rolls) tap left to release the statue after you to get the right distance between you and the statue, now you can place the statue on the pressure plate to open the gate with you right infront of the gate. L-roll to go through and have the statue void
The last gate before the boss door can be skipped with a bomb boost although this is not used much. To do this place a bomb in the set location and clawshot at the back of the target, if done correctly you should get knocked on top of the gate.
