The "Two by Two" advancement, found in the Husbandry tab, challenges players to breed every breedable animal in the game. Completing it grants 100 experience points and the satisfying title "Breed all the animals!" This is a parent advancement to none but requires prior progress in breeding at least one animal for the prerequisite "The Parrots and the Bats."
In Java Edition (latest 1.21+), there are exactly 26 specific mobs you must breed a pair of. Bedrock Edition mirrors this list closely, though achievements are profile-locked while Java advancements reset per world. Trader llamas do not count toward llamas, and mules cannot breed themselves but count when produced by breeding a horse and donkey.
Breeding Basics
To breed any mob:
- Locate two adults of the same type.
- Feed each their specific breeding item while they are close (within 8 blocks).
- Hearts appear, they enter love mode, and a baby spawns after a short animation.
- For egg-layers like frogs, turtles, or sniffers, you do not need to wait for eggs to hatch.
- Tamed mobs (cats, wolves, horses, etc.) must both be tamed first. Use leads or boats to transport mobs safely.
Prepare a checklist in a book and quill or use commands like /advancement query to track progress.

Step-by-Step Strategy
- Start Easy: Breed farm animals (cows, sheep, pigs, chickens) on a plains base. Grow wheat/seeds/carrots.
- Tame Companions: Wolves, cats, horses/donkeys/llamas. Stock bones, fish, golden foods.
- Explore Biomes: Use an elytra or Nether highways for jungles (ocelots, pandas), mountains (goats), deserts (camels, rabbits), swamps (frogs), beaches (turtles).
- Rare Ones: Mushroom Fields for mooshrooms (boat across oceans). Lush Caves for axolotls (strip mine Y=-59).
- Nether Trip: Potion of Fire Resistance for striders/hoglins. Build safe paths.
- Special Cases: Sniffer eggs from ocean ruins brushes. Mule last via horse/donkey. Armadillos in savannas.
- Verify: Open advancements; all 26 grant the pop-up.
Pro Tips
- Transport: Boats for water mobs, leads for land, minecarts for caves. Nether portals for quick travel.
- Farms: Auto-breeders for commons; wandering traders sell tropical fish buckets/seeds.
- Dangers: Armor up for hoglins; powder snow for striders if needed.
- Multiplayer: Each player tracks individually; share bred babies.
- Checklist Apps: Use external trackers for progress.
With patience and exploration, you'll unlock "Two by Two" and fill that Husbandry tab. Happy breeding!
