Dragon

No. Gold is the only mutation confirmed by name, and the confirmed change is the golden color. One session's top earner had a Gold label, but a golden capybara earning 12 and a Golden Retriever were removed as low earners during a cleanup. Keep or sell by the cash number on the animal.

The official line is to shoot eggs across the map. No biome list or coordinates are documented. A Solar Event option can show in the menu, and what it adds is not documented.

No working code and no expired code is confirmed, and a redeem control has not been documented. The empty list means nothing trustworthy is published yet. It does not prove the game can never have a code.

The game says Rebirth multiplies everything and reaches the locked guns. No source states a cash cost, a stat requirement, or what is wiped. In one session the button could be tried around a $3,000,000 balance, ignored the first press, and worked later. Read the button in your server.

A cracked egg despawns if it is not placed on your plot in time. One session lost an 80,000 HP Space Egg on a slow walk home. Carry the pickup straight back and set it down before you shoot the next egg.
