How to get Two by Two

1. Breed every breedable animal at least once - around 20 species including cows, sheep, pigs, chickens, wolves, cats, horses, donkeys, llamas, rabbits, turtles, axolotls, frogs, goats, camels, sniffers, armadillos and the rest. Mules do not count as separate (they come from horse + donkey), and yes, hoglins and striders count too.
2. Most overworld farm animals are straightforward: pen two of each and feed them their food.
3. The rare ones plan around: turtles (seagrass, beaches), sniffers (torchflower seeds from archaeology, then breed two sniffers), axolotls (tropical fish buckets, lush caves), frogs (slimeballs), hoglins (crimson fungi, they attack you), and pandas/foxes/polar bears variants.
4. Nether animals need to be bred in the Nether: hoglins and striders (warped fungi).
5. Keep a checklist - the advancement does not tell you which species you are missing.

Tips

Start a breeding ranch near spawn and ship rare pairs home with leads and boats. Sniffers are the long pole: you need two eggs from brushing suspicious sand/gravel in warm ocean ruins and trail ruins, so check our archaeology guide.
