Simon the Belt Snake

anonymous asks: Do you guys know anything about Simon the snake? I wanted to find out if it was a canon magical item, or homebrewed by Matt. I don't think anything has been mentioned about where Vax found it, or if it can do anything other than just turn into a real snake. I asked on twitter, but I don't expect a reply. Do you think that if Simon went to 0hp as a snake, it would just revert into a belt again? Or that the magic would be nullified?

With the exception of a few notable items, Matt tends toward the resources already been made available by manuals. Our research found this wondrous item in Pathfinder, which seems to be a pretty good descriptor of Simon. In that case, it would revert back into belt form if it was reverted to 0 HP, or if it traveled too far away from Vax.
