Spike at Bedazzled has a Creepy Crawlers TV commercial. I had one of the orginal Creepy Crawlers kits when I was a kid. I think it might have been the best toy I ever owned. Nearly forty years later, I can clearly remember the wonderful smell of Plastigoop.
They still make Creepy Crawlers, but the "Thingmaker" cooker is now a crappy plastic box with a light bulb heating element and a safety door that won't let you see your creepy crawler cook. Also, the Plastigoop smells completely different — quite unpleasant. I feel sorry for kids these days.
