The Exotic Animal collection system has been redesigned in our latest update. You may now use Bronze, Silver, Golden and Epic tickets to purchase Exotic Animal chests, in addition to being able to purchase them with Gems. The cost of each Exotic Animal category has been rebalanced to only require a single Bronze, Silver, Golden or Epic ticket. Any tickets that you may have had previously, have been automatically refunded as Gems and will be received when you claim our team’s update message from your Mailbox in the game.
