Cobbreeding is a game-mechanics mod that adds full Pokémon breeding functionality to Cobblemon, letting compatible Pokémon in your pasture lay eggs with proper IV, nature, ability, and egg move inheritance for Minecraft Fabric, Forge, and NeoForge.
One of the biggest gaps in the Cobblemon experience has been the absence of breeding. In the mainline Pokémon games, breeding is a cornerstone mechanic — it's how competitive players optimize IVs, hunt for shinies, and pass down egg moves. Without it, Cobblemon feels incomplete for anyone who wants to go beyond casual catching. Cobbreeding fills that void entirely, transforming the pasture block into a functional breeding center. With more than 5 million downloads since its 2023 release, it has become one of the most essential companion mods in the Cobblemon ecosystem. Whether you're a casual player who wants baby Pokémon or a dedicated breeder chasing perfect IV spreads, this mod delivers a faithful recreation of breeding mechanics inside Minecraft.
Key Features of Cobbreeding
- Full IV Inheritance with Held Items — Cobbreeding replicates the mainline games' IV inheritance system, including support for Power items and the Destiny Knot. This means competitive breeders can methodically work toward perfect IV spreads just like they would in an official Pokémon title, giving Cobblemon a genuine endgame breeding loop.
- Nature and Ability Inheritance — Parents can pass down their nature using the Everstone, and abilities transfer to offspring following familiar rules. There's even a small chance for eggs to randomly receive a hidden ability, and parents with their hidden ability can pass it on normally. This opens the door to breeding rare hidden-ability Pokémon without relying on pure luck in the wild.
- Egg Move Inheritance and Mirror Herb Support — Every move a parent has ever learned counts toward egg move inheritance — they don't need to have the moves actively equipped. On top of that, the Mirror Herb item can teach egg moves outside of breeding. This is a huge quality-of-life improvement that saves time and eliminates the tedious move-juggling that frustrates breeders.
- Shiny Hunting via Masuda and Gen 2 Methods — The mod implements shiny-boosting methods inspired by the Masuda method (parents with different original trainers) and the Gen 2 Crystal method (shiny parents boost shiny odds). Dedicated shiny hunters finally have a reliable, skill-based path to finding shinies rather than depending entirely on random encounters.
- Pasture Block Egg Spawning — When two compatible Pokémon breed successfully, an egg physically appears in the nesting area at the bottom of the pasture block. You simply walk up and pick it up. This tangible interaction makes breeding feel integrated into Minecraft's block-based world rather than being a detached menu system.
- Inventory-Based Egg Hatching — Eggs hatch over time while sitting in your inventory, and the timer pauses when you store them elsewhere. Abilities like Flame Body and Magma Armor reduce hatch time by half. This encourages you to carry eggs with you during adventures, turning every mining trip or exploration session into passive breeding progress.
- Pokéball and Form Inheritance — The Pokéball used to catch the parent passes down to the offspring, and regional forms inherit directly from the parents rather than being determined by biome. Collectors who care about matching Pokéballs and specific forms will appreciate this level of detail in the inheritance system.

Frequently Asked Questions
Does Cobbreeding work on multiplayer servers?
Yes — Cobbreeding fully supports multiplayer. Compatible Pokémon placed in the same pasture will breed even if they belong to different players, making it ideal for community servers where trainers can collaborate on breeding projects.
Do I need Cobblemon installed for Cobbreeding to work?
Yes — Cobblemon is a required dependency. Cobbreeding extends the pasture block that Cobblemon provides, so the base mod must be installed first. Without Cobblemon, the mod will not load.
Can I shiny hunt using Cobbreeding?
Yes — the mod includes two shiny-boosting methods. The Masuda method applies a 4x shiny boost when the parent Pokémon have different original trainers, and the Crystal method boosts odds when one or both parents are shiny. Server owners can also configure the exact shiny multipliers.
Is Cobbreeding available on CurseForge?
No — the developers have chosen not to upload Cobbreeding to CurseForge for personal reasons. The official download is available on Modrinth. However, you can still include it in CurseForge modpacks as an external mod without any issues.
Can I configure breeding speed and egg hatch time?
Yes — Cobbreeding offers several configurable options. You can adjust the minimum and maximum breeding time in ticks (defaults are 8,000 and 14,000), the egg hatch speed multiplier (default 1.0, where lower values mean faster hatching), and the shiny boost values for each hunting method. This gives server administrators full control over how breeding feels for their community.
