As you walk through Button House, Humphrey's headless body walks past you. It bumps into you, and it jumps back a little before continuing to walk past, likely looking for its head. It had its arms out as it walked around, clearly not having a single clue where it was or where it was going. It couldn't speak and definitely couldn't do anything else without its head. Maybe you could follow after it and help? Or maybe just watch. Just don't corner it, it gets scared...
