This morning the international version of the Tsum Tsum mobile game was updated to add the new Under the Sea Treasure Hunt event!
This event is similar to the Easter event where you have missions to complete to progress through a series of cards. Some of the missions will be "Treasure Chest" missions where you will collect Treasures to add to your collection. Once you have collected all the Treasures you will get a silver Little Mermaid event pin!
We have create a Little Mermaid: Under the Sea Treasure Hunt Event Guide which you can find by clicking here
Also, as part of the event you can get a Scuttle Tsum Tsum by completing cards!
