Cambot is one of the bots from Mystery Science Theater 3000, though he's only seen for a few seconds during the "Robot Roll Call." This is the version seen from seasons 5 through 10.
Like my other MST3K bot plushes, Cambot is for sale. I've only made him in one size so far, but I would be happy to make him in any size that you like.
Cambot is 4 inches tall, 6 inches long (from back to camera lens) and is $25 (plus shipping)
I also make custom plushes. So if you have a character that you would like in plush form, feel free to contact me (you can find more info in my journal [link]
