Does the Royal Egg use cash?
The HATCH [E] button shows a hexagon and 79, not a dollar sign. The Frost Egg world label is the one that says $10000.

The Royal Egg panel
Standing at the Royal Egg opens a grid titled ROYAL EGG. Five portraits sit in the grid. Each one has a name and a percent. Nothing else on that grid names a sixth result. The button under the grid says HATCH [E]. Under the words, a hexagon icon sits next to 79.
The 79 is the number on the button. The game does not call it gems on this screen, so this page does not either. It is a different price from the green cash prices on the index and from the Frost Egg's $10000 label.

The five rates on the grid
Read the percent on the portrait, not a rounded guide. Ancient Protector is 36.4%. Air Wyvern is 28.4%. Electric Wyvern is 20.5%. Flame Wyvern is 9.1%. Galaxy Rex is 5.7%. Added up, those five figures come to 100.1, which is what you get from rounding each one to a tenth. There is no room on this panel for a hidden sixth prize.
These names do not appear on the Dino Index. Galaxy Rex is not Tyrannosaurus, and Ancient Protector is not Titanhorn. If you want index stats, use the dino list. The egg only tells you the hatch chance.
| Result | Percent on the portrait |
|---|---|
| Ancient Protector | 36.4% |
| Air Wyvern | 28.4% |
| Electric Wyvern | 20.5% |
| Flame Wyvern | 9.1% |
| Galaxy Rex | 5.7% |
What a 5.7% hatch means in plain counts
Galaxy Rex is the rare end of this table at 5.7%. That is about 1 in 18 hatches if the panel's percent is the true chance and each hatch is independent. At 18 hatches you are not owed a Rex. You are around the average, which is still a coin-flip-or-worse away from a guarantee. Ancient Protector at 36.4% is the result you should expect to see first.
The panel does not show a pity counter, a luck bonus, or a duplicate rule. Those stay off this page until they are on screen. The button price of 79 is the cost of one hatch in that frame, not a bulk discount.
Frost Egg is a world label at $10000
Out on the grass, a blue label reads FROST EGG with $10000 under it. That is a cash price floating in the world, the same kind of green-and-white money text the shop uses, with a dollar sign. It is not the Royal Egg grid and it does not list hatch percents.
Other base labels in that shot belong to other players. They are not Frost Egg prices. Use the words FROST EGG and the $10000 directly under them. Do not copy a neighbor's VALUE number onto the egg.
Eggs the HUD names, without a menu
During a fight, small world labels also say FROST EGG and ROYAL EGG near the plots. The top bar does not become an egg shop. You still have Shop, Stop or Fight, Base, and 1x. The egg screen is the one you get by going to the egg, not a tab in the index.
The official game text says your egg is on the dino menu and tells you to protect the egg. It does not print an egg HP number. No egg HP is listed here.
What not to add to this table
A blurry frame was once read as an egg-destroyed banner. The clear frames of the Royal Egg do not show that sentence, so it is not a mechanic on this page. Codes are not listed on the egg either.
Index colors do not map onto these portraits. Ancient Protector's portrait is yellow and Galaxy Rex's is purple, but the panel does not call them Legendary or Epic. The only words to copy are the name and the percent.
FAQ

Are the hatch dinos in the 33/33 index?
Their names are not on the index cards we copied. The index ends the dino list at Titanosaurus. Ancient Protector, the four wyverns, and Galaxy Rex are egg results.
