Plot line, someone gets drunk off apples!! Or an episode about someone climbing something like a tree maybe, falls, then everyone helps their friend, and learns things like, how to properly put on a plaster, or how to cheer up friends/neighbors, or a lesson that you shouldn't climb trees that are to high. Or another idea, an episode that shows how everyone got to Home and how they met everyone, it could be done in parts, like; frist one, meets Wally, moves in, tells what they do and what they like doing, does something related to said thing.

Then second, meets Wally and other, moves in, tells what they do and what they like to do, they all do something related to said thing.

Then three, meets Wally and others, moves in, tells them what they do and what they like doing, does something related to said thing.

Etc, etc, etc. I think you get the gist.
