Fern

Fern is an alraune blessed Nephelym, who lives in front of the Ranch She helps the Breeder to harvest semen and milk, and can be allowed to suck on your tits or dick for 150 shinies (Orgasium)

After allowing Fern to collect your fluids 30 times, sleeping will upgrade Fern to Phase 2.

Allowing Fern to collect your fluids an additional 70 times (100 total) then sleeping will upgrade Fern to Phase 3.

Due to the nature of Fern's species she becomes immobile in phase 3 and will no longer be able to assist around the homestead or dig up Shiny to reward the player for giving fluids.

She produces an offspring called Blossom, who will help you harvest semen and milk.

These phase upgrades come with new animations for each type of activity as well as new dialogue and responses from Fern. Alraune seem to increase in intelligence with this phase growth as Fern no longer speaks in her primitive manner in later phases.
