Super secret bonus answer?

That explains the increase in his reappearance. For a while I caught him daily, haven't seen him in a little while now. There was 1 day I caught him 4 times...

If there's any truth to this topic, I am believing this is the answer to that secret bonus found in the files.

I love when it says he appears in your town, and the camera follows him around. Wow, you are totally being secretive and completely hidden that I'm following you around.
