Kids hatch their own triceratops, stegosaurus and T. rex—no time machine required! They simply submerge a “prehistoric” egg in water, then watch as it cracks to reveal a baby dino within 72 hours. The dino continues to grow in the water, expanding and morphing until it fully breaks out of its shell! You get 3 different eggs; each measures 4 1/4" tall.

These were fun to watch as they hatched slowly over a few days. The dinos that came out of the eggs were impressively large!

My boys loved watching them grow over the course of 24-48 hours. Such a good lesson in patience for young kids. We let them dry out and have put them back in water for them to grow again.
Yes, I would recommend this product.

T-Rex hatch and grow
September 23, 2023 - By Lindsey Bairdfrom cherry hill, nj
Such a wonderful treat to keep my kids occupied. Be sure to keep the hatched dino in the water for a long period of time to see the dino grow even more! Absolutely love this product!
Yes, I would recommend this product.

Not great
September 19, 2023 - By Lori Jfrom Southern California
Not a great set, what 3-5 year old is expected to have the patience for 3 days of slow egg hatching?
Took too long, they were sort of sticky once finally hatched. Still wrinkly.

Watch and Grow Fun
May 19, 2023 - By Angie Martinez-Heffner
my grandson is fascinated with all things dinosaurs right now and this was something he looked forward to checking every morning until it hatched and then his excitement grew even more. We had the best time with the hatch and grow dino eggs. We will definitely be doing these again!
Yes, I would recommend this product.
