Complete Level 30 and you will unlock "Trips".
Through Trips, you can send your dolls to various locations around the world.
Dolls sent on trips will return after a set amount of time has passed.
On their return, the doll's Faith level will increase, and you may also be able to collect photos and items.
Dolls currently on trips will not be able to join you for puzzle levels.
*To send a doll on a trip, you will need Trip Points.
