A bag of holding is from DnD. It is a bag that hold a infinite amount of things. In this game it is holding creatures or "babies". You can see the character "catching" them in the bag of holding. Which you use them to create a village.
Thanks
Do you know how to create a village? and then I have a lot of these babies
You need to put a drill on a tile,and after that you can put a village on the same tile.
