The Treasure Hunt was a feature introduced in 2015. It gave players a chance to search for items and gems. The Treasure Hunt gave players a chance to have more than five keys (default number of keys) by purchasing more animals. On May 29, 2019, players could watch a short video ad for an extra 3 keys.
On April 29, 2020, the feature was discontinued, replaced by the Daily Spin.
Each animal treasure hunt contained one primary treasure chest and multiple secondary treasure chests. The secondary reward often consisted of different quantities of Gems. Less often one of the secondary rewards would be a sapphire. The primary reward was 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.
