Active Cattle-tree mutation

Udder. Wouldn’t require the threshold.

Functions similarly to the Aero-Evaporator CBM, but produces milk at the expense of your own hunger, thirst, fatigue. Wouldn’t be able to make a “profit” with it – The cost would outstrip the production.

Practical. Several recipes require milk, and it gets increasingly harder to come by.
