Worm Hole

Worm Holes are essentially living tunnels which connect two points in the world together. They appear as mouths in the ground which open when approached. When the option ‘Jump in Worm Hole’ is selected Wilson will leap inside and be spit out the other end after a brief delay. There are multiple Worm Holes in most worlds and they always connect the same two places on the map. Often they will end in two completely different areas with different resources, such as a Forest (with lots of Trees) and a Savanna (with lots of Grass and Boulders).

Traveling through a Worm Hole causes a Sanity loss of 15. Sanity can be quickly drained by repeatedly jumping into them. Smallbirds and Pigs will follow Wilson through a worm Hole, as will Chester if the Eye Bone is in your inventory. Many objects, such as Food, Gravedigger Items, and Wooden Thing components can be dropped into the Worm Hole, and will be spat out the other end.

Sick Worm Holes
Sick Worm Holes are dying and have limited (possibly only one) uses. Once these Worm Holes are used up they shrivel up and die. They look similar to their healthy counterparts but their "skin" and mouth are a more yellow/green tint as opposed to a healthy red.

Trivia

 * Wickerbottom refers to the Worm Hole as "Megadrilacea Oraduos."
 * The sick version of the wormhole was added in the "Doorway To Adventure" update.

Bugs

 * Giving Worm Hole Wooden Thing components will crash the game.
 * Opening the map at the same time the player is jumping in a Worm Hole will cause the Worm Hole's animation to never finish.
 * The other end of the Worm Hole can be in the water. However, the player cannot get onto walkable ground until the player goes back in the Worm Hole.
 * Jumping into a Worm Hole with sanity below 40 will skip the animation/sound and show the screen moving to the other end of the worm hole, where, it will show the character leaning over with their hands on their head (which players will do occasionally on low sanity), and then play the animation of the player emerging from the Worm Hole.
