Sinister Wood is a type of wood that was introduced during the 2015 Halloween Update, along with Spook Wood, and became an annual occurrence every successive October. It is the most elusive tree in the game; out of a 100 Spook Trees, only one may spawn.

Similarly to Spook Wood, this tree is generally sold among players, used for blueprints, or duplicated due to its unique neon color and rarity. Disclaimer: The Lumber Tycoon 2 Wiki does not support duplication of any kind!


Sinister trees use the same growth variables as Spook, commonly growing twisted, bent and complex, but it is modified to have a granite exterior with a neon interior, along with being much rarer. It is a misconception that Sinister grows differently than Spook, originally being believed that Sinister tended towards thinner branches, but this is not true. The planks also have a neon material, which emits an orange glow.

As of Halloween 2020, the bark exterior of Sinister Trees was changed to granite, once again giving it the ability to reflect light to the camera. To identify if a tree found is a Sinister instead of a Spook without chopping it down, look to see if the exterior has a unique texture, as Spook trees have the texture Smooth Plastic, which is textureless.

Unlike Spook Wood, Sinister Wood is not as heavy as it.


The tree grows on any material named Ground, Road, or Slate (in Roblox Studio).

  • Slate: any rock or cliff in the game, color does not matter.
  • Ground: typically grass that trees grow on in their respective biomes.
  • Road: any road in the game. Excluding the Safari road.

A major misconception about Sinister hunting is "hot spots" that it grows in. Sinister trees will tend to grow in areas with more parts that it can choose from, typically around the Swamp, the Mountainside, the Taiga, and the Tropics.


Spook Wood, along with Sinister Wood, typically began to grow when Defaultio announced "It's about to get spooky" on Twitter. However, he did not tweet this in 2017 and after, and it is unlikely that he will either in the future.

From 2015 to 2018, sinister trees glowed a very noticeable gray color, although this was just what neon black looked like at the time. It was very easy to identify if a tree was a sinister rather than a spook from very far away. Then, in 2019, Lumber Tycoon 2 switched to the new Future is Bright Roblox lighting engine. Sinister trees lost their gray coloration with this and looked identical to spook trees at first glance. The only way to identify if a tree was a Spook or not was to check if any part of the tree reflected light back at the camera. The bark was still set to neon black at this time, and one of this materials properties is it wouldn't reflect light to the camera, and stay completely black with all angles. In 2020, Roblox removed the option of creating neon black materials. Defaultio then decided to change the material of the Sinister tree's bark to a black granite texture, and looking for that is now the only way to identify a Sinister pre-chopping, as Spook bark is Smooth Plastic.
