The Garden Gnome Farmer is a tiny, chicken-sized peaceful gnome that wanders your farm, tills dirt and grass into moist farmland, and plants crops like wheat, carrots, potatoes, beetroots, and melon and pumpkin stems — it even plants a random seed after fertilizing or on empty farmland and is immune to explosions, fire, and lightning. Tame one with any seeds to have it follow or sit; tamed gnomes speed up nearby crop growth, harvest mature crops (including melons and pumpkins), store harvests in a persistent 27-slot chest-sized inventory, will walk to and deposit items into nearby chests or barrels, and a Creative spawn egg that looks like a villager egg with a red pointed hat and blue overalls lets you spawn them directly.

The Infernal Axolotl is a tiny, demonic axolotl (half the normal size) with glowing red eyes, charred skin, and tiny horns that never spawns naturally and must be summoned with a spawn egg or command. Hyper-aggressive, it attacks all nearby beings within a 20-block radius and now scurries across land at terrifying speed—far faster than a sprinting player—while remaining fully amphibious and able to stay on land indefinitely. It can be leashed with a normal lead that won’t snap as it strains to pursue targets, and the lead can only be removed by directly interacting with it. Works best with the full Murder on The Vine modpack I made. This thing is a monster... beware. For that reason, you can only summon by command, use a command block and lever for safe and quick spawning.
Henri Viktor is a rare dwarf-like character that spawns in plains and forests with an aqua-blue nameplate; you can also summon him with a nerdy blond-afro spawn egg decorated with glasses, a book and an emerald that emits blue particles when held and plays a page-turning sound when used. His face now shows very pale skin, bright blue eyes and bright brown-blonde hair with a lutin-like youthful, impish expression while his outfit and body remain the same. When you come within five blocks he stops and asks one of over 50 trivia questions across Minecraft, D&D, Lord of the Rings, German, nuclear science and piano—answer in chat to win rewards from emeralds to legendary items (hard questions greatly increase chances of Netherite Blocks, Dragon Eggs, or the Henri Viktor Sword or Wand), but answer wrong and he transforms into a terrifying, fast sword-wielding hunter that screams and chases you; you can also craft Henri Viktor's Glasses to get an X-ray–style mineral finder that grants night vision, highlights nearby ores and shows their coordinates.

The Beast Wolf is a nightmarish, corrupted wolf with grotesque zombie-like features and an eerie red glow; it's fiercely territorial and attacks on sight, boasting high health and savage bites. They now spawn extremely rarely and appear in small packs of 2–3 anywhere in the world, day or night. They can only be tamed with a Nether Star, becoming loyal pets that follow, sit, teleport to and defend you, and have a 25% chance to drop a Beast Wolf Head trophy when killed by a player.

The Corrupted End Stalker is a grotesque, glitched End-like undead that stalks and relentlessly attacks players on sight, covered in bloody textures and digital artifacts and boasting a massive 400 health pool that makes it extremely hard to put down. It always drops a Glitch Shard on death which can be combined with a Blaze Rod and a Breeze Rod to craft the Glitch Shard Sword — a powerful blade that deals 12 attack damage and inflicts Slowness III and Wither II on any player or mob hit for 6 seconds.
The Hauntburst Creeper is a terrifying boss about one and a half times larger than a normal creeper, with a haunted black-and-red appearance that can spawn in the Overworld both day and night (but not on Peaceful). When it explodes it unleashes a massive blast and, after the blast finishes, five Mini Hauntbursts appear in a ring around the detonation and scatter outward and upward; these minis are faster, more aggressive, and often trigger chaotic chain explosions. Defeating the boss drops Haunted Gunpowder used to craft devastating Haunted TNT and a powerful Haunted armor set and sword — Haunted TNT now behaves like regular TNT when lit or powered, waiting the normal fuse before detonating while still producing a massive haunted blast (it can chain more quickly if set off by another explosion), the full armor greatly reduces explosion damage, and the sword creates a contained blast that deals 45 to 55 damage to nearby mobs only without breaking blocks or harming dropped items.
The Haunt King Zombie is a towering four-block-tall boss — a haunted undead behemoth with twice the health and attack of a regular zombie, immune to sunlight, that can spawn naturally in the Overworld even during the day or be summoned with a scary haunted-face spawn egg; in combat it summons waves of fast, baby-sized Mini Haunt King Zombies to overwhelm you. Sometimes the Haunt King appears as a Haunt King Zombie Jockey riding a massive Big Zombie Spider — a large hostile undead spider that attacks players and also drops Haunted Flesh — and both the jockey and spider have their own spawn eggs and spooky visuals. Defeating the boss, its mini minions, the jockey, or the big spider yields Haunted Flesh (with a small bonus chance if killed by a player), which can be crafted into an extremely durable Haunted Armor set that grants high protection, extra toughness and knockback resistance and can be repaired using Haunted Flesh.
The Haunted Ender Colossus is a terrifying giant Enderman about two blocks taller than normal with 80 health; immune to water and able to breathe underwater, it constantly teleports during combat, can launch players into the air, inflicts blindness with each strike, and will become aggressive if you look it in the eyes. It spawns from a distinctive haunted-creeper-style egg with dark green to near-black colors and eerie cracked markings in the Overworld at any time, and when slain it drops 4–6 Haunted Ender Pearls used to craft a powerful armor set and sword — wearing the full armor grants continuous night vision, the sword now blinds only mobs (stopping them from seeing or attacking while blinded), and blinded creepers lose their targets and won’t start their fuse or explode until they can see again.

A majestic Allay adorned in ornate Italian-inspired jewelry and golden armor, the Roman Jewel Allay is a luxurious, Roman-styled guardian. Its protective aura prevents Zombies, Creepers, Husks, Skeletons, Endermen, and Strays from spawning within a 30-block radius, making it perfect for safeguarding your base. Can be tied to fences with a lead so you can tether it where you need protection. Works best with my full modpack Murder on The Vine.
The Hauntweaver Broodmother is a terrifying oversized boss spider about 2.5 times a normal spider, with 100 health, heavy armor and strong knockback resistance; her venomous bite poisons and every ten seconds she summons Mini Hauntweavers that entangle victims in sticky cobwebs, and she can appear naturally in the Overworld even during the day. When slain she drops Haunted Webs (with extra webs if killed by a player), which can be crafted into a powerful full Haunted Web armor set, a high-durability Haunted Web sword, and a durable Haunted Web bow that fires empowered arrows. You can craft Haunted Arrows that deal double the damage of normal arrows, and wearing the complete Haunted Web armor set prevents you from getting stuck in webs and lets you climb and stick to walls (hold sneak while against a wall to stick).
The Haunted Arrow Lord is a towering skeletal horror nearly 3.5 blocks tall that hunts you day and night, firing deadly five-arrow volleys in a rain pattern and periodically summoning smaller minions to overwhelm you; it's immune to sunlight and drops stacks of Haunted Bones (with a bonus if slain by a player), which can be crafted into very strong armor, a powerful sword, a Strong Haunted Bone Bow with Haunted Bone Arrows, and a Haunted Bone Multitool that works as sword, axe and pickaxe and deals 50 damage. The mod also adds a giant Haunted Skeleton Spider large enough for the Arrow Lord to ride — non-mini Arrow Lords will summon and mount these spiders, and free haunted spiders will seek out full-size Arrow Lords to carry them; the spiders also drop Haunted Bones to help with crafting.
