Heh, imagine that. Maybe Marten has something similar? I mean, if something like that suddenly landed on my head to monitor my physiological responses to questions, I'd freak out too. It may very well have influenced the results that made him end up with Pintsize.
Also, Glassybot seems to only have two... erm, well I can't call them "phalanx bones", since they're not bones, but yeah.
On a random note, did you know the fourth/ring toe is the only toe that doesn't have its own Wikipedia page?
