That's a very specific number. But, then, maybe there was a lot of market research that preceded the creation of this advert, which promised kids THRILLS & CHILLS...WHEN YOU SEE 7 AMAZING PLANT CREATURES COME TO LIFE!

So what this actually was, was a bunch of crummy plants that were shaped crudely into the form of scary monsters.
