Well, I had Pietro today and he said he'd move in. He'd BETTER! His colours are so cool and he'd fit in with my weirdly coloured town.
ETA - if I may, I have a question regarding this. Why do the campers at first refuse and refuse? Why is it such a battle to get one to stay? Granted, this is the first time I tried for so long, but most always end up saying no repeatedly. Why?
Lucky and it was surprisingly easy to get him to move in.
I think it's just random, I had a couple campers suggest and agree to move in after introducing themselves lol.. The longest one for me took about 20 minutes. Marina
