This Mega Growth Egg Dino of over 20 centimeters grows into a dinosaur with a size of more than 50 centimeters! How? Place the egg in cold water and wait 24 to 48 hours. Then the shell of the egg breaks and the dinosaur grows. Make sure that the water always remains above the edge of the egg. Even if the dino has completely emerged from the Mega Growth Egg Dino, leave it in cold water. Until he's fully grown... and then you'll have a new dinosaur friend!
