For all methods, it is useful to know that Mikau's walking cutscene begins when he touches the shore. Because of his rising and falling animation in the water, it is possible for him to be in a position where the cutscene hasn't triggered yet but will trigger when he reaches a low part of his animation.
On the English version, playing SoDT while Mikau is in a position where he will touch the shore at the bottom of his rising and falling animation will start the walking cutscene as the game fades for the SoDT cutscene, skipping the walking cutscene.
Between pulling out the ocarina to learn NWBN and the song staff appearing, there is a 1f window for any input, and additional frame afterward when it's still possible to pause. NWBN is already in the inventory by this point, so to skip the cutscene, either
and then soar away. Because this is larger than a 1f window, many runners choose to mash start or start + ocarina rather than timing the input. The video below demonstrates mashing start and shows that NWBN is in the inventory after pausing.
The first of the two tank fish to eat four bottled fish will eat the other tank fish and spit out the heart piece. (Strat info needed.)
Hookshot to the top of the target to grab and climb. Pull a bomb and shield drop it near the far side of the hookshot target. Target walk left before the bomb explodes to the edge of the platform. Once the bomb explodes, hold up-left to long jump to the next platform. From there, a recoil flip can easily reach the heart piece platform.
Use the torch to hookshot clip, then hold down and roll to get to the door to the mask room. This is useful for getting to the heart piece if the skulltula tokens aren't needed.
This grants access to the heart piece without the mask puzzle being solved. Jump onto the mantel as shown. Use a bomb to get ISG, then hover once and backflip onto the blue mask. Recoil flip from near the top of the mask and hold right to curve Link's trajectory left into the stairway.
Superswimming to Zora Hall is faster than swimming and can be done using a leever that spawns at night. Aim a backwalk just left of the Zora Hall tower to get hit by the leever, backwalk a few more steps, then recoil flip when it attacks to land in the water and begin superswimming. The superswim can be directed to the front or back of Zora Hall.
It is possible to skip the cutscene of the turtle rising by pause buffering one frame at a time between playing New Wave Bossa Nova and reaching the load zone for Zora Hall.
The first pause in this cutscene skip is frame perfect, as there's only one frame for input between playing the song and the cutscene beginning. One way to time this start press is watching the song textbox and reacting to one of its elements disappearing. The c-button notes disappear on one frame, then the textbox disappears on the next frame.
Hookshotting the turtle's left tree far enough to the left side will cause Link to land in an area that doesn't trigger the cutscene of going to Great Bay Temple. From here, we can skip the cutscene by activating timestop, touching the cutscene trigger, deactivating timestop near the load zone for Zora Hall, and then pause buffering to enter Zora Hall to prevent the cutscene from triggering. This skips not only the cutscene of the pirates' shipwreck but also some of the cutscenes of the turtle leaving Zora Hall and arriving at Great Bay Temple that usually play on the first visit to the dungeon.
As seen in the video above:
This Zora high ledge grab saves time reaching the fairy fountain. If you fail this, you can climb onto this platform with a Zora transform ledge grab.
See additional notes from Imbued.
Target the wall around the spot shown in the video, then punch. Goron pound to pop up to the heart piece.
Without following the seahorse, it is still possible to get to the eels by following the invisible path. This can be done by following the signs underwater, but dolphin dives are faster. Demonstration
Demonstration (see video description)
The fastest way to leave Pinnacle Rock is to void out, and it is faster to do so by clipping through the wall near the final eel rather than swimming up and into the fog.
