A friend of mine had one of these. They didn't work well. The first time you warmed up a squashed thing it unfurled pretty well, but they never quite squished back into a square. After the 4th or 5th unfurling, the creatures developed hard spots, and you basically couldn't squash them again. Also, terrible as toys. All you could do is unfurl and squash. Not much fun to someone old enough to do the heating and squashing dafely.
