Bringing 80 New Creatures to Minecraft with Alex's Mobs

What This Mod Adds

Vanilla Minecraft has plenty of wildlife. Cows on the surface, fish underwater, the occasional zombie ruining your evening. Even so, the default roster starts to feel thin once you have logged a few hundred hours. That is where Alex's Mobs steps in. The mod drops roughly 80 brand new creatures into the world, ranging from coastal birds that hassle you for sandwiches to whales that genuinely move with weight in the ocean. Uploading mods on HolyHosting is quick through the panel, so this walkthrough covers the full setup on both the server and your local client.

Quick Mod Profile

Alex's Mobs is maintained by sbom_xela on CurseForge, with art handled by Carro3DSculpts. Supported versions span 1.16.3 through 1.19.1, and total downloads have already crossed 19 million. Some additions stick close to real biology, while others lean into folklore and pure fantasy. Each creature comes with its own behavior, drops, and a deliberately vanilla-looking style, which makes them feel native rather than tacked on.

Downloading the Mod

  1. Open the Alex's Mobs page on CurseForge.
  2. Click the Files tab near the top.
  1. Scroll until you find the Minecraft version you actually play.
  2. Hit the download button on the right side of that row.
  1. Save the `.jar` somewhere you will remember in five minutes.
  2. Grab the matching version of Citadel as well. It is the library that powers many of the mod's mechanics, and skipping it is the most common cause of crashes.

Installing on the Server

  1. Open your control panel and stop the server before touching anything else.
  2. Open your panel's version selector on the main page.
  1. Confirm the server is running the Forge version that matches your downloaded mod.
  2. Switch to the file manager in your panel sidebar and log in.
  3. Find or create the `mods` directory, then step inside it.
  1. Use the upload button at the top, then drag both `.jar` files (Alex's Mobs and Citadel) into the window.
  1. Wait until each file shows 100 percent, then go back to the main panel.
  2. Start the server. Forge will boot, and the mods will load alongside it.

Installing on the Client

  1. Make sure Forge is already installed for your version of Minecraft.
  2. Launch the Minecraft launcher and open the Installations tab.
  3. Hover over your modded installation and click Open Folder on the right.
  1. Inside that folder, locate or create a `mods` directory.
  2. Drop both `.jar` files into it.
  1. Back in the launcher, press Play.

Forge and Alex's Mobs will finish loading, and once the main menu appears you can join your server and start meeting the new residents.

First Steps In-Game

The first spawn comes with a gift: the Animal Dictionary lands in your inventory automatically. Flip through it whenever you run into something unfamiliar. Each entry covers behavior, preferred foods, and taming requirements. Skimming a few pages before wandering off saves a surprising number of pointless deaths.

A Tour of the New Wildlife

There is no way to cover all 80 creatures in one guide, but a handful deserve a proper introduction. Each one behaves differently and drops unique loot.

Cachalot Whale

A neutral ocean giant that often hunts squid. During thunderstorms, Cachalots sometimes beach themselves and need a hand getting back to the water. Helping one out can reward you with Ambergris, which fishermen villagers trade for emeralds, or which you can craft into an Echolocator.

Seagull

The opportunists of the coastline. They will snatch food straight from your hand or hotbar and happily munch anything you drop. If a seagull is carrying a map, bribe it with a Lobster Tail and it will fly you toward the chest it leads to.

Elephants

Elephants travel in herds containing calves, tusked adults, and tuskless adults. The tusked ones hit hard and can charge. Calves and tuskless adults can be tamed, ridden, and even outfitted with a chest for storage.

Grizzly Bear

These large omnivores wander forest biomes, usually with cubs in tow. They turn hostile quickly when you get too close. A grizzly that has recently eaten honey is much calmer, and at that point you can try taming it with salmon.

Comb Jelly

Found drifting through frozen oceans at night, the Comb Jelly is a calm splash of color in dark water. Defeating one can drop Rainbow Jelly, which applies a flashing rainbow effect to whatever (or whoever) you use it on.

Sunbird

A serene crane that glides above the highest peaks. Reaching it grants a blessing that improves Elytra flight and lets you float up and down. Attacking it has the opposite effect, leaving you cursed with extremely fast, extremely fatal falls. Any undead mob that wanders too close bursts into flames on contact, which is a handy detail in its own right.

Troubleshooting

The server kicks me with an error on join. Usually a missing mod or a version mismatch. If the message names a specific mod, fix that one first. Otherwise, double-check that the server and client are running identical versions of every mod and of Forge. Restart both ends and try again.

The game crashes on startup. Almost always a missing dependency. Alex's Mobs needs Citadel. If either side is missing it, or the versions do not line up, the launcher will refuse to cooperate. Match the versions on both ends, restart, and you should be set.
