I looked back at the free SUPERNATURALS PREVIEW COMIC a few posts back (a lucky 50p Geek Shop find) so I thought I'd follow-up with one of the toy commercials.
This is an American TV spot and - as I recall - the British ones were (slightly?) different. I don't recall if the footage was the same (they actually manage to make the toys look pretty neat) but I'm almost certain that the British ads featured a short, sung, jingle along the lines of "Soooopernaturals". It's stuck in my head for decades, despite my almost-total contemporary lack of interest in both the toys and the comics. That's the power of advertising!
