Nope, it wasn't a Star Wars item. I don't know much about it really. My parents have a couple of plastic bins of restaurant premiums in their junk room. Some of the toys in there date to when my college-age niece and nephews were kids, and some are from meals they bought for my kids in the last dozen years, and for my great-nephew in the last three years.
As for what restaurant, again I am not sure. They usually stick with McDonald's, sometimes they go to Burger King. I wouldn't rule out Jack's or Wendy's either.
I saw this robot years ago and rescued it as a possible Star Tours/Star Wars custom junkbot, off in the background of a diorama. I never got around to doing anything with it. I just happened to be reorganizing my Star Tours collection earlier this year shortly after watching the Muppets trailers, and a light bulb went off.
