Biology Dictionary
Every Minecraft world is teeming with creatures, and keeping track of them all can feel like a full-time job. The Biology Dictionary add-on turns that chaos into a clean, searchable encyclopedia. Whether you are a survival purist, a modpack creator, or a builder who needs static NPCs, this mod gives you one screen to solve dozens of mob-related headaches.
What Is the Biology Dictionary?
The Biology Dictionary is a vanilla-friendly book that collects every mob you encounter into a single, browsable catalog. It adds no new blocks or entities. Instead, it uses NBT data to turn a standard writable book into a powerful inspection tool. The book reverts to a normal writable book if you uninstall the mod, and reinstalling restores it. That means your world stays clean and your save file stays safe.
The mod works with vanilla and modded mobs alike. Discovery happens automatically, so you never need to set up anything manually. You can track which mobs you have found, which are still waiting, and even record how, when, and where you first met each creature.
Discovery and Progress Tracking
Multiple Discovery Rules
Not every player wants the same experience. The Biology Dictionary offers several discovery modes:
- All unlocked — every mob is visible from the start.
- Vanilla kill statistics — discovery ties to your existing kill counts.
- Biology Dictionary system — the mod tracks discoveries on its own.
You can also configure what counts as a discovery. Detail screens, telescope observation, interaction, and kills can all trigger a new entry. By default, undiscovered mobs hide their details, but you can switch to a pure collection layer if you prefer.
Entity Highlight and Telescope Discovery
Rare targets can be hard to spot. The entity highlight feature marks nearby mobs of the same type, with configurable ranges and costs. A telescope sighting can even count as a real discovery, rewarding careful observation.
Inspecting Mobs in Detail
Entity Details and Tags
Open a mob page and you get a full breakdown. Overview pages show default or reference data, while detail pages show the live state of the entity you are looking at. You can inspect base stats like health, air, effects, speed, jump strength, hitbox, and whether the mob counts toward spawn caps.
Ecology data covers habitat, loot tables, edible items, tempting items, and leashability. Variants include horse markings, panda genes, villager types, and more. Behavior state shows AI, invulnerability, silence, persistence, portal cooldown, growth, breeding cooldown, and love status. Special mob data reveals villager schedules, restocks, job sites, bee hives, dolphin moisture, screaming goats, pet owners, and wandering trader despawn timers.
Entity Skills
Inspection is only half the story. The Biology Dictionary lets you modify mob behavior directly. You can lock growth, block breeding, control portals, disable AI, force persistence, mute mobs, force restocks, retain traders, gift pets, and even get spawn eggs. Skills require XP, items, permissions, or Creative mode by default, and every cost is configurable.
If you want a smoother way to manage all this, the foxygame.net launcher offers one-click installation for the Biology Dictionary, so you can jump straight into your encyclopedia without wrestling with manual file placement.
Special Screens and Controls
Inventory and Beehive Access
The mod includes dedicated screens for supported mob inventories. You can view, take from, or fill them. In Survival, that counts as stealing, so stay out of the target's sight. A separate beehive screen lets you inspect honey level, bee count, and the bees inside. This is perfect for stopping villagers from picking up wheat or checking which hive your bees flew home to.
How to Open the Dictionary
The Biology Dictionary is built around screens. You can open it by right-clicking while holding the book or by pressing the hotkey, which defaults to the semicolon key. Survival players need the book unless configured otherwise, while Creative players can always open it. What you look at determines the screen:
- Block or air — home screen
- Entity — that entity's detail screen
- Beehive — beehive info screen
- Straight up — forced home screen
- Straight down — your own detail screen
How to Install and Obtain the Book
If you are wondering how to install Biology Dictionary, the process depends on your loader. The mod supports Fabric, NeoForge, and Forge. Fabric requires Fabric API and Cloth Config. NeoForge and Forge require Architectury API and Cloth Config. Once installed, obtaining the book is simple. In Creative mode, you can find it at the end of the Tools and Utilities tab. In Survival, you can buy it from Wandering Traders. The sell chance starts at 100 percent and gradually drops to 20 percent over about two real-time days, so early-game players have an easy time finding it. Pack authors can disable trader sales in the config and add their own recipes instead.
Mod and Datapack Support
Developers and pack creators are not left out. You can add or override mob descriptions through resource packs and manually adjust spawn biome and structure descriptions via datapacks. The mod is compatible with virtually all modded mobs, and extension support lets mod developers integrate their own creatures seamlessly. Every modification has a resource cost, keeping the experience balanced and respectful of vanilla game design.
Final Thoughts
The Biology Dictionary is more than a reference tool. It is a complete mob management system that respects your world, your mods, and your playstyle. From tracking discovery progress to muting noisy chickens and locking baby mobs, it solves problems you did not know you had. If you want to download Biology Dictionary for Minecraft and turn every creature into an open book, this mod deserves a permanent spot in your loadout.
