Skyward Sword
Miscellaneous Glitches
Bush Teleport
Some bushes that Link can carry around get drawn and updated by an actor called V_Clip. V_Clip is an actor that either allows the bush to load, or to unload. If you enter a V_Clip that unloads bushes while holding one in your hands, the bush will unload but Link will still be carrying something invisible. If Link is carrying an invisible bush, making the camera point towards where it unloaded allows you to get a lot of speed and perform a jump. This requires geometry to exist between your current position and the position where the bush unloaded. This technique can be used in Lanayru Desert to get to the Lanayru Gorge early without the use of Back in Time for example.
Areas that contain both bushes and V_Clip are: Skyview, Faron Woods, Lanayru Desert, Shipyard and Lanayru Gorge.

Ledge Clipping
Discovered by Venick
Actors that push Link around without being pushed by him can push Link out of bounds while he is hanging from a ledge.
Death Clipping
Dying and getting revived with a fairy can allow Link to fit through slightly smaller gaps than usual.
Fairy Void
When dying with a fairy in a bottle, the game will start an internal timer, and wait until Link is grounded before reviving him with the fairy. If Link can't get grounded for whatever reason before that timer runs out, the game will proceed to void Link out, and respawn him at his last safe position.
Shielding Stance Glitch
Discovered by Kazooie and Akheon
Long Jump Attack (LJA)
Discovered by Kazooie
In Skyward Sword, it is possible to get a long jump attack by targetting something that is standing above ground that is higher than you. It does not give enough extra distance to have many uses in speedruns: its main use is in the Wisdom Room of Sky Keep where it helps to avoid using the double clawshots.
Clean Cut Minigame Rupee Glitch
While the Clean Cut minigame owner only asks for 10 rupees in the US 1.0 version, you actually need 20 rupees to play it. This was patched in later versions.
"Game Breaking Glitch"
This glitch is famous and prompted Nintendo to release a patch. This only occurs on 1.0 versions of the game. After meeting with Levias, complete the Lanayru Song of the Hero quest. Once that is done, go back to the Lanayru Mines and talk to Golo again. This will set the flag that you have started the Lanayru Song of the Hero quest again, despite the fact that you've already completed it. This makes it impossible to start the other quests.
Contrarely to popular belief, the glitch is not related to doing the Lanayru Song of the Hero quest first. It can also happen when doing it second.
On the following versions, this glitch was patched. The way it works is the following: Golo checks for if you've watched the Lanayru Gorge Intro Cutscene to know if he should congratulate Link for finding the dragon's territory, or if he should give you a hint to find it. On US 1.0, talking to Golo after watching the Lanayru Gorge cutscene triggered the Lanayru SotH quest. This causes the game breaking glitch if done after finishing the Lanayru SotH quest. On the other versions, triggering the Lanayru SotH quest only happens by talking to Golo before watching the Lanayru Gorge intro cutscene, which fixes the softlock (since it is impossible to finish this song of the hero quest before watching the lanayru gorge intro cutscene).
Event code
As seen in the event code, the game checks if you've watched the gorge into cutscene on line 247. 4 story flags are flipped when talking to Golo after watching it on US 1.0 (lines 252-255). On subsequent versions, they are only flipped before having been to the gorge instead (lines 270-273), fixing the glitch.
Loftwing Tutorial Zelda Textbox glitch
Discovered by peppernicus
Trigger a textbox during the Zelda tutorial (by picking up a rupee, or activating the life tree seedling for example). When Zelda attempts to talk to Link again, it will trigger the textboxes with ids that follow the textbox you just triggered. This is a funny effect but it is unfortunately useless.
Pouring Water on a Chu Crash
If you attempt to pour water on a Chu, the game crashes.
Post-Credits Deathwarp
On the US 1.0 version of the game, if you save your game on Hero Mode after defeating Demise and watching the Credits, your savefile will be saved in Hylia's Realm, but your respawn stage will be set to the final credits stage, which is the Sealed Grounds Spiral with the Statue of the Goddess. Thus if you load your game after saving on that prompt and die, you will respawn on that Sealed Grounds Spiral stage but on the layer used for the cutscene (layer 13) and you will be able to listen to the harp music.
This was patched for all other releases of the game.
