About the Hellion's Sniffer+ mod

Welcome to Hellion's Sniffer+! This is a 1.20 Expansion mod building on features surrounding the Sniffer. This includes new behaviors for the Sniffer itself; several new plants for it to dig up, including a new woodset; and an entirely new cave biome, housing all these wonders! Hop in and explore!

  • Sniffers now can be saddled and ridden
  • Sniffers can now have chests equipped
  • Sniffers with equipped chests will place dug up seeds in their chest
  • Sniffers can be given an Ominous Banner to carry you to the nearest Outpost
  • Several new plants including Ivy, Stone Pine Trees, and Fiddleferns
  • Torchflowers now emit light, earning themselves their name
  • And an entirely new cave biome, the Timeless Grotto

I am developing this project completely on my own in my free time. If you would like to help support the work I do and get special benefits like early betas, special previews in the Discord, and a cosmetic in a future mod project I have planned, please consider becoming a Patron!

How to install Hellion's Sniffer+

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.20.1–1.21.1 on Fabric, Forge or NeoForge automatically, together with its dependencies: Dependency.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 1.21.1. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file snifferplus-NeoForge-1.21.1-1.0.1.jar (219 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Dependency.

  4. Launch the loader profile

    Open “Mods” in the main menu: Hellion's Sniffer+ should be in the list.

On a server

  1. A server on Fabric, Forge or NeoForge

    The mod only works on a server with the same loader and game version, for example 1.21.1.

  2. File goes into the server’s mods folder

    Stop the server, put the mod file into the mods folder and start the server again.

  3. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
