Fake American: Both Button Mash and his mother are voiced by British actors.
Fan Nickname: Button's Mom has been called, among other things, "Caring Heart" and "Love Tap" by fans.
One of Us: Button is the obvious example, though his mother also plays games and even speaks the fictional language Humgolian. "I was young once, too!"
Screwed by the Lawyers: Hasbro issued a cease and desist on the series which forced Jan Animations to take it down. This has put a huge delay on the next episode as they essentially create new designs and Flash puppets for every single character. Although recently, Hasbro did allow Jan to re-work on his animations again, but it's unknown for sure of Button will stay the same.
Jan later on posted a video explaining that in all actuality, Hasbro themselves didn't know about the C&D, that it was rather their lawyers that issued it. Never the less, Jan and Hasbro have been recently talking through emails, and from what he said, they're striking a deal that will "satisfy both parties".
Tragically, Hasbro sadly declined Jan to allow him to continue Button's Adventures, although Jan is still thankful for the fans who supported him through and through.
