Event animals are animals that could only be obtained through a limited time event. These animals are not released permanently. There are two methods to obtaining event animals within events: by purchasing them with limited time currency from the event shop, or from a boss mission that can only be played in the event. The boss mission can only be attempted a maximum of 3 times per day, although VIP players receive more attempts for higher VIP levels.
Once event animals have been purchased or tamed in the event boss mission, they are found in an identical manner to regular animals. To get the baby animal, the player has to search in the stampede for a 'match' after the adult has been purchased, and ride the 'match' for a specific amount of time to begin breeding the baby. Once the event expires, the player can still obtain the content from that event in following events, most namely, the next anniversary event, which is a chance to catch up on any missed animals and hats.
