Trivia

 * 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.
 * The No Round Shapes Allowed cape may be a reference to the YouTuber Mysticat, who is known for a circle using only command blocks in Minecraft. This is mainly supported due to the background of the cape matching the YouTuber's skin.
 * The "181 Choices" splash doesn't exist in the  file, but is generated by the game on startup instead.
 * Rule and  contain a misspelling of lava, based off a bug that appeared in 22w44a.
 * Rule can be "Replace 'k' with 'K'", which causes the misspelling of "block" into "blocK", based off a bug happened in 20w45a.
