The DinoMazing Egg Decorator can make anyone into a paleontologist! Put one of the two mystery eggs into the machine and the unique spinning action will help create colorful designs while “egg-sposing” the cracks. Open the eggs to reveal non-sticky slime and a mystery dinosaur! Want to make your own dinosaur hybrid? Each mystery dinosaur has interchangeable limbs so you can do the dino swap! While the DinoMazing Egg Decorator comes with non-toxic markers, you can use any markers to decorate the eggs. The DinoMazing Egg Decorator includes 1 decorating machine, 2 Mystery Dino Eggs and 6 colorful non-toxic markers. Collect all mystery dinosaurs. Sold separately. 4 AA batteries required/not included.
