Icyclo
by happyfied
Icyclo is a world generation datapack that places icicles across cold biomes, and it can be loaded as a datapack or as a mod.
What it does
Icyclo places icicles in the cold biomes of a world, so they appear as the player explores snowy terrain. The datapack is the main way the effect is delivered, and it can be combined with other datapacks. A debug mode in the datapack gives icicles a glowing effect and prints debug information to chat, which some owners enable while testing a world.
The mod is published for Fabric, Forge, NeoForge and Quilt, and it is also available as a data pack for server platforms. Server owners install it on the server, while players may add it on the client for the full experience. Files cover 1.21.5 – 1.21.11 and the latest build, 1.1+mod for 1.21.11, was released on 2026-01-28.
