2015 Halloween Update
The 2015 Halloween update added some new items such as the Pumpkin, which could have been bought at Bob's Shack for $360 Money and currently serves no purpose besides decoration and Pumpkinball. The only way to currently get these now are by trading/buying from different users. In addition to this update, the rare Spook Wood and extremely rare Sinister Wood were also seen throughout the event.
2016 Halloween Update
The 2016 Halloween update includes the similar items from 2015, with the exception of the pumpkin. Now referred to as the "Dark Pumpkin" it has a black and purple look instead of the orange and yellow look from 2015. It also introduced Phantom Wood and the End Times Axe. In early October, the Preserved Enlarged Ostrich Eye was added to the game, it is currently the smallest and most expensive item in the game. On October 31st sometimes you can rarely join to a special server called End Times Server. Defaultio changed the entire look of the game to make it look more spooky. He added a sand fog. He removed all the tree leaves, removed some of the letters on shop signs, made all metal objects rusty, completely changed the Wood R Us sign, and more. On Halloween, players were able to get the End Times Axe by doing the Rukiryaxe quest and get to the End Times Biome.
2017 Halloween Update
The 2017 Halloween Update was generally similar to the previous year with the exception of the introduction of the Lost Cave. This dark tunnel can be found near the Taiga entrance including two new characters —— the Skeleton, found at the end of one cavern, and the Strange Man, at the end of another. The Strange Man will grant the player the ability to fill any blueprint with one cubic Unit of any wood. However, this ability costs $10,009,000 Money.
Similarly to the two previous years, October started off with a new pumpkin (the Strange Pumpkin), Spook Wood, and Sinister Wood. It lasted until the 31st of October, 2017, when the End Times theme was triggered again. On that day, in Merely's booth, a YouTube video ID to a teaser trailer of Defaultio's upcoming game was written on a poster, replacing the text "FOLLOW THE EAGLE".
