Parents Are Raving About Dolcate HydroHatch™
Join over 120,000 families who have brought the prehistoric world to life with screen-free, hands-on fun!
"My 4-year-old was obsessed with waiting for the egg to crack. Every morning he ran straight to the kitchen to check the glass and see how much his dinosaur had grown. A total hit and great screen-free entertainment!"
"I was skeptical about the 600% claim, but these dinos really do get massive! It kept my kids entertained for almost a full week just watching them expand in the water. We can't wait to hatch the rest of the pack."
"I bought the 6-pack for my grandsons and they haven't stopped talking about it. It’s so much better than just giving them another standard plastic toy—it’s an entire experience. Buying another set today."

Frequently Asked Questions
The magic usually starts within 12 to 24 hours! Once the egg is fully submerged in water, the dinosaur inside begins to absorb the water and expand, eventually causing the shell to crack open.
They really do get massive! After the dinosaur hatches, replace the old water with fresh water and leave the dino inside. Over the next 2 to 3 days, it will continue to absorb water and grow up to 600% of its original size.
Absolutely. Safety is our top priority. The eggs and the growing dinosaurs are made from 100% child-safe, non-toxic materials. Because of the size of the eggs and the resulting toy, we recommend this product for children ages 3 and up.
Not at all! Unlike sticky slimes, kinetic sand, or paints, HydroHatch™ only requires a simple glass or bowl of tap water. It’s a completely mess-free and stain-free experience that provides days of entertainment.
