Tree Warp

Tree Warp is a major glitch that warps you to the last underworld location you entered.

It is an application of Dynamic Sprite Spawn Overflow, described on the vanilla wiki, where loading the three sprites that constitute the pink tree with a face overflows the intended maximum number of sprites.

Tree Warp brings you to the inside of the most recent entrance you used with a falling animation. As a side effect, it re-closes all the chests on the last underworld supertile you were in, which is often the same tile as the entrance. This makes the glitch useful for duplicating items. (A consequence of this is that it trivializes any No Logic Triforce Hunt, without additional rules.)

If you tree warp to an EG2 tile (a small underworld location with one exit), you should save and quit from there. If you walk out the door, the game will freeze for up to 18 minutes while it tries to restore you to the location you entered from.

Setup

This guide shows one of the easier setups for Tree Warp. (The video on the vanilla wiki shows an older, less reliable setup.) The outline is:

• Have at least 6 arrows, 6 bombs, and 6 rupees so that the thief is guaranteed to spawn 6 sprites when it hits you
• Enter Village of Outcasts from the top center, making sure that the northern pink tree is loaded
• Get a thief and two cucco skeletons to a particular area, and make sure the spear-throwing moblin isn't there
• Let the thief bonk you to the right, which spawns 6 sprites and knocks you to a location where a second pink tree is visible, causing Tree Warp

• 

  The best place to start is at this entrance. The pink tree will stay loaded and count toward the number of sprites.

• 

  Kill the spear-throwing moblin. You can dash through it to prevent it from dropping anything, or collect what it drops.

• 

  Get this thief to follow you.

• 

  Herd the cuccos: throw one up (so that it bonks the hedge and gradually starts running away to the right), and throw the other right to catch up with it.

• 

  Chase the cuccos into this area.

• 

  Get the thief to continue following you.

• 

  Stand here until the thief bonks you. Note the column of tiles on the right side of the screen. If you go past this and see the edge of the tree, you went too far.

Bailing out

oh jeez, oh no, my cuccos are escaping

If you get a tree warp setup slightly wrong, so that the number of sprites on screen is off by one, turn around and leave the tile the way you came. If you continue with the tree warp with the wrong number of sprites, the game will crash. The crash may permanently affect your save data.

Tree warping to Link's House

If you haven't been to an underworld location since loading the game (for example, if you start at the pyramid), the tree warp will take you to Link's House. Also, when you enter Link's House using Tree Warp, it will be completely dark inside.
