I came across this commercial for a contest from Kool-Aid Bursts and Kay-Bee Toys, which says the grand prize winner would've won a Super NES game "starring you". I've never heard of this before. And a Google search turned up nothing.

Is it something that is known to actually exist? If so, it seems like it would be very rare.
