About

Wetland Whimsy is a mod which completely overhauls Minecraft's swamps! It includes a whole new subbiome, several new plants and blocksets, and ancient ruins that dot the landscape of these overhauled wetlands. While these ruins contain plenty of treasure, be warned - some of them may not be as abandoned as they first seem!

Features:

  • Overhauled Swamps with completely redone visuals!
  • The Marsh, an all-new biome that spawns between Swamps and the ocean!
  • New Flora in the form of Pennywort, Cordgrass, and unique mushrooms!
  • New Fauna, such as the friendly Cranes and not-so-friendly Infested Spiders!
  • New Building Blocks including Lemonstone and the all-new Bald Cypress woodset!
  • Wetland Ruins, ancient structures built from lemonstone with plenty of loot for those who look.
  • The Swamp Dungeon, a mysterious, mazelike structure built for an unknown purpose. Ancient Pots with strange symbols may be found down there... their loot may not be that great, but maybe there's a way to improve it?

Compatibility

Wetland Whimsy uses biome modifiers to modify the vanilla Swamp, meaning it should be compatible with most other mods that redo the Swamp biome as well! This is true for both the 1.21.1 and the 1.20.1 releases, so you don't need to worry about adding this mod to any of your modpacks.

Currently, Wetland Whimsy has explicit support for YUNGs Better Witch Huts, YUNGs Extras, and Supplementaries. Additionally, it has been tested with Nature's Spirit, Swampier Swamps, and Extra Compat, all with no isssues. If you are unsure if a mod will be compatible, try it out! The worst that could happen is that they aren't.

Version Support

Wetland Whimsy currently supports Neoforge 1.21.1. 1.20.1 is deprecated - it may recieve bugfixes, but most likely will not get any new content.

Unfortunately, this mod will not have official Fabric support. Maintaining one modloader is already difficult and time-consuming, two would be too much for me to handle. However, this mod is free and open-source, so if you know how to port it and would like to, go ahead!
