Hah, I am surprised it took so long for somebody to mention that. While making it I was aware it was a bit hand-wavey, but the place they are taken to was some kind of animal sanctuary, they weren't being held captive or anything. The humans were misguided, but not malicious (much like the other animals).
Also, I thought it was amusing that the mother could just walk home at any time, but I like to think she was simply too busy helping and knew her boy would keep things friendly at the village.
Thanks for playing!
