Eggs

Eggs are purchased to be hatched into pets, which boost the amount of taps players get. Super Rebirth pets also boost the amount of Super Rebirths players obtain per super rebirth.

Starting from The Mine egg, there is a very low chance to hatch a secret pet, which is much more powerful than the regular pets and has a different design/name (Starting with Crystal from the aforementioned Mine egg, secret pets from eggs added before the mime egg give the 2-4% pet with “Secret” (Black) rarity.)

Trivia

 * All eggs that were released prior to The Mine egg did not have a secret pet variety. To compensate for that, players are now able to hatch the rarest pet as a secret pet.
 * SecretEgg.png a secret pet is hatched, a red egg with a mystery sign on it is shown instead.
 * There was a glitch which allowed players to obtain secret pets from the boxing island egg really easily. (Patched). Eventually, the Wild West Island was also bugged with this during the Boss/Mothership update (Also patched.)
 * It was once possible to get secret pets without the “Secret” rarity via super rebirths, but adding on the buff to The Hive (Removal of the rarity change risk.), it is currently impossible to achieve this. It is still possible for these “Fake” secret pets to still exist as they weren’t changed back to the aforementioned secret rarity.
