Back around 1992, I recall a promotion for Cookie Crisp cereal where there was a little plastic Sonic figure in the box. They weren't painted or anything, just blue.
If there was some kind of special contest going on, I don't remember it very well. I couldn't have been older than four at the time... Now, I remember feeling let down, because I got a GOLD one.
I'm sure that I've since lost it, but it's been in the back of my mind ever since. ...did I win something?
