I came across a website that had information about a Chibi-Robo desktop buddy that doesn't appear to have been archived. It was up for download on Nintendo's Japanese website for the game back in 2005. It seems to be really obscure... I could only find one other mention of it in English. Does anyone know more about this?
Here's the download page for the widget. It leads to a 404 page, and there's no other captures. Note: You'll need a Flash emulator installed to access this, such as Ruffle.
