If the op was a bot, it sure picked a weird way to do it's thing.
Contra, I had some of those cars with keys, I think the were called "Burnin' Key cars". I had a set of those, I liked how the keys had fobs on them that had the vehicle makers "symbol"...or whatever it's called. I think they also came with a plastic drivers license? A company called Maisto either bought/renewed the license or simply made their own version using the same name a year or two ago.
PCS, the Micronauts were clear (at least some of them were), no water required. I loved those figures and still have mine from when I was little.
