I think they got the format wrong for this. Its a great idea, but it would be more interesting as a by episode discussion with the regular crew. Brian explaining his insanity to unwitting mates who know nothing about the series is going to get repetitive each week.
How weird would it be if the alligator/crocodile head originally went with Skullcruncher?
It does have that vibe, doesn't it?
These do seem to be super early designs though. They don't seem to have worked out how the head connects to the shoulders yet, so they've all got different necks that would never have worked (quite a few have the animal heads as the pegs, which, no)
