Like Like GlitchFrom description:
The fundamental part of this trick is to get caught by a like like while infinite diving, like what you do before getting any item on c as Zora. This will cause the like like to slide all over the place (in a way you can't control) and spit you out. [Note: I didn't slide around much in this video. Typically you're going all over the place... it depends on how fast you mash B.] You will be unable to move until the like like eats you again. If you kill it, you will be stuck forever.
Now, one of three things can happen at this point. You will either be stuck hovering in the air, hovering under the water, or on the sea floor.
The first two are worthless. You can only switch between link and Zora, you cant use any items, and if you backflip or sidehop, you'll be stuck until you switch to another transformation.
The third is where the magic happens. To do this, make sure the like like has one hit (unless you have glitched boomerangs (Zora with Weird B activated gets off Epona with sword), which kills a like like in one hit). Mash B as the like like slides around, and if it spits you underwater, you will likely hit it while grounded, killing it. You now have limited movement.
You now have 2 options:
1) Work your way up to shore with B, turn around, and use b to "walk" across the top of the water.
2) (What I did in the video) Go to the shore until you're in "floating mode" and do the "any item on c" glitch as Zora. You are now free to be any transformation underwater, go anywhere underwater, and use every item underwater. There are tons of weird effects, most of which are left out (and result in making you reset).
I did include the hookshot oddity. If you use it, the game goes insane trying to figure out what to do next, locking it until you reset. Dive timer is on and off and super slow. Drowning does absolutely nothing to stop this.
