Recently I've been brainstorming. Here's what I've come up with.
-Theme park! Include the tire bench, playground equipment, and fun patterns. Also have a fossil dig site and a hide and seek area with lots of trees and pwp's. The houses could be like a petting zoo, food court, gift shop
-Food themed town! Have multiple houses themed to be a bakery, sweets series, cooking classes, etc. Have these villagers: Merengue, Zucker, Tangy, Apple, Maple, Frita among others
