Each Tsum Tsum will be characterized in different ways, it could be a brown tsum, she could have a ribbon in her hair, he could have white hands, etc. The reason that this characterization becomes important is when we attempt to complete missions. The mission could be from a bingo card or it could be for a monthly event but, some missions will require you to use a certain Tsum characteristic in order to complete it.
I will list the various characteristics and you can click on each category to go to a page displaying every Tsum within that category.
Hopefully it will make the missions grinding a bit easier.
