Is it possible to use someone else's Shampoodle? o.o
Yes.
If you do not build the campsite, your 10th villager will be a villager from someone else's town. The 10th villager does not always have to be a camper.So even though this has been talked about a lot I still need clarification.
So, if I DO NOT add the campsite, my town will remain with 9 villagers? However, if I DO add the campsite I can invite the person in the tent to come live in my village ( meaning they can't just invite themselves in )
