Tame a bunch and make a penguin farm for poly. Nine females to one male works great. Set up a bunch of ACs and have them on wander when the babies hatch club them. Free poly within the comfort of your own base!

(I laughed too hard when I did this)

You can carry them on any flying mount and stay warm in the snow biome if you live there or need to collect resources because of there ability to warm up its surrounding area.

The babies taste best
