So it took THIS LONG to finally get Ref Calves? That's crazy, but glad to see them.
Now this could be interesting, we'll have to wait till the Pen is released, but it seems to point to this building working way different than the previous 5 habitats.
No Feed or Bottled Needed? And a Glowing Calf, I may actually build a few of these.
Then there is this Bobbing for apples thing that could be something.
Spoiler: So far there is no sign of this critter doing anything special. Basically it seems like a recolor but doesn't have a unique foal, at least as of yet.
