This is awesome! How'd you do it? Feel like sharing?
For the bear part, he spawn just spawn beside my newly built cabin tiles.
Just simply throw stone/rock to the bear to get him to follow you into the house.
Club him until unconscious while he in the house.
Deconstruct the door.
Kick his skull again.
Start to build the wall with windows.
Stop building every 30 minutes to 1 hour to kick/punch the bear skull to make sure he dont wake up.
Voila, you now have a bear in the house.
But sadly, the bear will be despawn/dissppear after some times when his timer expired.
Strangely, the bird never get despawn, maybe its located in the village instead of the wilderness settlement.
I even got lucky enough to capture a Npez Maiden in her village. She seem to be ok. Never get despawn.
