These dinos were only available as prizes for events and cannot be found by any other means.
With the exception of the six purchasable eggs, all Rare and Super Rare Egg Dinos have only been available through events.
Certain tickets provide event-exclusive dinos, namely the Quantum Dino Cage and the Celestial Dino Cage. All SS rare dinos in these two cages have the same stats as the original SS but have a different colour, usually black but also gold. Even event exclusive SS from earlier events can be found in these cages.
