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.
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 ledge grab saves time reaching the fairy fountain. If you fail this, you can climb onto this platform with a Zora transform ledge grab.
