wonderland.jar
Wonderland.jar, a Forge mod for 1.20.1, adds strange anomalies that stalk players and try to pull them into a dimension called Wonderland.
What it does
Some anomalies in the mod follow the player and eventually attempt to take them into the Wonderland dimension. Leaving Wonderland may not leave things in the main world unchanged, since conditions there can worsen afterward. Progress is slow and varies between worlds: the first visit can come early in play or only after many in-game days.
Entity frequency is set with a 1 in X value, so a setting of 3 means a 1 in 3 chance and a setting of 24 means a 1 in 24 chance. Raising a spawn value therefore makes the entity rarer, not more frequent. The mod requires Geckolib, which must be installed alongside it. Files are published for Forge 1.20.1 only, with the latest file 3.0.3 dated 2026-08-28. The environment is client and server, so the server and every player need the mod, and it is released under All rights reserved, which means it is not open source.
