-After first settling in your town, advance time by one day, then backwards, then forward. Repeat this and more neighbors will have moved in your town quickly.
-When you visit other towns, you might meet a new friend. If you really hit it off with one of the locals, he might decide to move to your town. If he likes his new home, your town might soon be flooded with even more neighbors. Note: This often works with Opal the elephant and Camofrog the frog.
