Propagator: 5 Per Tribe
Requires Element to operate.
Breed creatures from cryopods (your tribe's tame limit will be thankful).
Mutations and the stat they happened on can be easily identified on the tooltip of the offspring in the Propagator.
Mammals will lay eggs when breeding that way. (Note: QoL+ does not provide cryopods)

Farmer:
Requires Calien Soup to operate, or a Tek power source.
Collects fertilizer from nearby Compost Bins and Dung Beetles and distributes it to nearby Crop Plots.

Nanny:
Requires power to operate.
Feeds baby creatures until they reach 15% maturation. Put food in the Nanny's inventory and it will automatically distribute valid food to nearby babies.
Imprints little by little nearby non-adult creatures. (Known replication issue: the meter might not update in multiplayer, reconnecting or leaving the chunk will make the real imprint progress appear)

• May not Work with Certain Water Tames.

Gardener:
Requires Beer to operate, or a Tek power source.
Collects what nearby Crop Plots generate.

Ammo Box:
Stores ammunition and distribute them to nearby turrets.
