Anna

Anna is a Premium Box Tsum Tsum.

Information
Anna is a Random Transformation Skill Tsum Tsum. In addition to transforming random Tsum Tsum into Elsa Tsum Tsum, any chains created with the Elsa Tsum Tsum will also clear Tsum Tsum surrounding that chain. Her base number of Elsa Tsum Tsum created is 4~7. Although she creates Elsa Tsum Tsum, she does not count as a "Call a Friend" Tsum Tsum (possibly because Elsa is her sibling rather than a friend).

Strategy
Like Maleficent, it's best to try to get the longest chain possible of Elsa and Anna Tsum Tsum. Do not pop bubbles close to Elsa Tsum Tsum, because the Tsum Tsum will just be destroyed without clearing surrounding Tsum Tsum.
