## Introduction<\/p>\n
**Biology Dictionary** is a **utility** Minecraft mod for viewing detailed information about mobs and modifying certain mob properties. This mod **does not add any new blocks\/entities**, and can be safely uninstalled\/reinstalled at any time, or when upgrading Minecraft versions.<\/p>\n
> Strictly speaking, this mod adds a book item. However, the book is implemented using a writable book + NBT (now called “components”). After uninstalling the mod, it becomes a regular writable book. Reinstalling the mod will restore its functionality.<\/p>\n
This mod was originally designed to enhance the experience for **technical survival players**, for example:<\/p>\n
– Highlight entities within 100 meters to easily find rare mobs like parrots and pandas
\n– View horse jump\/speed stats to quickly find high-performance horses
\n– View items that can attract\/feed mobs for easier taming and breeding
\n– View villager work sites to help locate trading halls
\n– Block mobs from\/force instant teleport through nether portals for easier mob transport
\n– Mute entities to avoid revealing decoration builds (e.g., chicken swings made with leads)
\n– Prevent baby animals from growing up to keep them cute (conveniently, `26.1 Snapshot 2` implemented better baby animals, making this feature even more useful!)
\n– Modify villager inventory items (presented as “stealing”) for automatic farm designs
\n– Remove mob AI and make invincible for NPCs or decoration builds
\n– View honey and bee information in bee hives
\n– And much more<\/p>\n
However, technical survival players sometimes don’t care about mod aesthetics. I still hope this mod can be as immersive as possible and blend into vanilla game mechanics, so I added some lightweight settings and created a relatively immersive UI. Players need to pay a reasonable cost to modify entity properties.<\/p>\n
> But my pixel art skills aren’t great. Contributions to improve Biology Dictionary’s UI are welcome!<\/p>\n

This mod currently only supports Fabric and requires **Fabric API<\/span>** and **Cloth Config API<\/span>**. As development progressed, this mod seems to have drifted quite far from its original intention (enhancing technical survival experience), so some might ask why I didn’t develop it for Forge, as many Forge mods add new mobs, and this mod seems useful for viewing attributes of those mobs.<\/p>\n This mod currently supports **Fabric**, **Forge** and **NeoForge** loaders.<\/p>\n – Fabric versions depends on **Fabric API<\/span>** and **Cloth Config API<\/span>**. ## Detailed Features and Settings<\/p>\n This mod is a complete restructure of **Bole**, as I wasn’t satisfied with the previous implementation. **Biology Dictionary** is essentially a full rewrite of **Bole** without adding too many new features.<\/p>\n ### Obtaining and Using Biology Dictionary<\/p>\n #### How to Obtain Biology Dictionary Item<\/p>\n – In Creative mode, find it at the end of the “Tools & Utilities” category #### How to Open Biology Dictionary Screen<\/p>\n – In Creative mode, simply use the hotkey (default `~`) to open the Biology Dictionary screen #### Screens for Different Targets<\/p>\n – Aiming at an entity opens that entity’s detail page ### All Supported Properties Display\/Modification<\/p>\n The following lists all supported property display and modification features by entity class hierarchy:<\/p>\n – **Entity** To display or modify the properties and states of mobs.<\/p>\n","protected":false},"featured_media":31123,"template":"","meta":{"_minecraft_slug":"biology-dictionary","_minecraft_project_id":"S3ELyJhj","_minecraft_author":"xienaoban","_minecraft_license":"LGPL-3.0-only","_minecraft_downloads":7311,"_minecraft_follows":36,"_minecraft_client_side":"required","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"biology-dictionary.zip","_minecraft_size_bytes":92448860,"_minecraft_version_count":85,"_minecraft_updated_at":"2026-05-16T23:51:52.132020Z","_minecraft_date_created":"2026-01-16T03:31:46.118822Z","_minecraft_date_modified":"2026-05-02T15:50:08.140510Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/biology-dictionary","_minecraft_icon_attachment_id":31123,"_minecraft_imported_at":"2026-06-01T13:33:59+00:00","_minecraft_import_hash":"15767ddee214a4a81b5be6031f5fe831","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[87,97,104,89,137,158,92],"mod_loader":[99,106,160],"minecraft_version":[36,37,41],"class_list":["post-31122","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-adventure","mod_category-fabric","mod_category-forge","mod_category-game-mechanics","mod_category-mobs","mod_category-neoforge","mod_category-utility","mod_loader-fabric","mod_loader-forge","mod_loader-neoforge","minecraft_version-1-20-1","minecraft_version-1-21-1","minecraft_version-1-21-11"],"yoast_head":"\n
