Even though we all remember playing with those Creepy Crawler machines when we were kids, they were at one point considered an incredibly dangerous toy!
The toy was around long before many of us were born. It was actually released back in 1964 under the name Creepy Crawlers' Thingmaker.
It came with a little oven that you would use to cook up your chemicals, but the super hot temperature of the oven was only half the problem.
While giving your kid an oven that reached 350 degrees is dangerous, it was nothing compared to the chemicals they were breathing in. The gel you used to make the bugs was called "PlastiGoop" and it was super dangerous.
Plastigoop came in a bunch of different colors and would harden into the plastic-like texture we all remember. The problem was that while the chemicals were being cooked in the super hot oven, it would give off noxious fumes that could make kids sick.
