When breeding, there is a small chance that a Kairon will try to steal one of your eggs by entering your den.  If you fight and win, you keep your eggs and you gain one Kairon random geno. If you lose, one of your eggs will be stolen.
You can Summon Valentino for some help, instead of fighting with your own Kai!

Thief - Kairon can only appear in a 5% chance IF the parents are:

• Not a Kairon

• S rank

• A starter OR owned by the player
  
  

When breeding a Kairon:

• Thief - Kairon encounter won't be triggered

• Can obtain a random egg (that was stolen by the Kairon breeding)
  
  

Quick battle: Instead of a full battle, you can decide to make the admin roll two dices (one for the Kairon, and one for you) and the higher ones wins. It is risky, as you have a 50% chance of loosing.
