Never saw it, but I LOVE slushies! I still get Slush Puppies. They're the best slushies ever and for some reason you can't find them anywhere anymore and if you do it's usually not the old machines where you make them yourself. We have only one very old, sort of hole in the wall convenient store near my house that is the only place with the original slush puppy machine! I go there for them all the time.
I'd love to have my own, but I have yet to find one that measures up to the slush puppy.
