Trivia

 * Bartek Bok showed a video of a minecart with 3d wheels 3 years ago.
 * The Wob item either appears to be a reference to a common crafting misconception. A post about this was made on Twitter that tagged the YouTuber PhoenixSC, who made a concept for this and seems to be the inspiration for the feature.
 * The Trails & Tails rule could also be a reference to a PhoenixSC video based off a mispelling of the update's title in an article on the official website. The typo since has been fixed.
