The Treasure Hunt is a feature that was introduced in 2015. It gives players a chance to search for items and gems. The Treasure Hunt gives players a chance to have more than five keys (default number of keys) by purchasing more animals. On May 29, 2019, players can watch a short video ad for an extra 3 keys.
Each animal treasure hunt contains one primary treasure chest and multiple secondary treasure chests. The secondary reward often consists of different quantities of Gems. Less often one of the secondary rewards will be a sapphire. The primary reward is a clothing accessory or den item.
Until December 2015, Rare items could be won through Bunny, Wolf and Arctic Wolf Treasure Hunts. In 2017, some Rare items could be won through the Fox, Penguin and Horse Treasure Hunts as they were given Traveling Salesman variants.
