I found this tow at the gift shop at Crackle Barrel Restaurant. My kids love dinasours so when I saw this I knew I had to get it for them. It is an egg that is about the size of a large orange, but shaped like an egg. The direction say to complete submerge it in water and watch it for the next 12 to 72 hours. After about 12 hours the egg starts to crack and continues to crack and break open for the next 72 hours. After about 72 hours the dinasour hatches out of the egg. If you leave the dinasour in the water for the next 2 days it will continue to grow even bigger. My kids and the whole family just loved this. It was so fun checking on it ever few hours and watching it crack and crack and finally hatch and then watch it grow. After it was big enough my kids were able to play with it, and continue to play with it a lot. It was exciting looking at the box and trying to guess and wonder what dinasour would actually be in our egg. I would highly recommend this fun toy for all ages.
