So Harley wasn't going to leave at all! He was just trying to get some peace and quiet. And he would have gotten away with it, too, if it weren't for those meddling Billy and Pete.
What's interesting about Pete is how he's changed over the course of the strip. Towards the beginning, he was a stupid, sissy turtle, and while he is still kind of dumb today, he has become a lot more complex. He is a very sympathetic character, caring about the environment as well as other people, but most notably he hangs out with Billy a lot now. Before in the strip, Pete would only have small conversations with Billy, but nowadays the two are always affiliated in stories, just hanging out or going on adventures. Of course, these are only a couple bits of Pete's personality. There are many aspects of these characters that I don't even understand (That's probably a bad thing if you're trying to keep consistency, heh).
Anyway, this ends another Billy the Pop story. Hope you liked this one!
