I've read reviews for years but never wrote one. This toy was so bad I just had to write one. I wish I had read the reviews before purchasing this toy. It does not work. No cars, not even hot wheels will launch or fit through the track. It did not fit together completely and keeps falling apart. The slime is ridiculous. You figure they would develop some thick slime which could come off the cars and the track. No, it's watery and you can't clean it up. One use and I tossed it out, of course after it stained the carpet.[...]
