Anna

Anna is a Premium Box Tsum.

Information
Anna is a random transformation Tsum. In addition to transforming Tsums into Elsa Tsums, any chains created with the Elsa Tsum will also clear Tsums surrounding that chain. Her base number of Elsa Tsums created is 4-7. Although she creates Elsa Tsums, she does not count as a Friendship Tsum (To qualify as a Friendship Tsum, the Tsum's skill must involve the creation of its friend - Anna fulfils this criteria, but she is not a Friendship Tsum).

Strategy
Like Maleficent, it's best to try to get the longest chain possible of Elsa and Anna Tsums. This way, you can farm a lot of coins. Do not pop bubbles close to Elsa Tsums, as the Tsum will just be destroyed without clearing surrounding Tsums this way.
