Lego and Animal Crossing seem like they would be a great fit. Depending on how you count there are almost (or more) than 500 villagers that appear in the video game series. One of which is named Octavian. In Animal Crossing he is known as a cranky octopus who is really into outer space and aliens. The octopus type of villager is one of the more rare types to visit, making Octavian rather special. This Lego Octavian is the creation of Dave Foreman. Everything is official Lego pieces, and on the purple cone is a custom star that probably took a lot more work then expected.
If you are looking for something similar, there is an old Lego theme called Fabuland, which shares a lot of concepts. Animal villagers living and working around town.
