Mater

Mater is a Premium Box Tsum.

Information
Mater will clear random Tsums with his hook. His skill is considered a  Tail-Swishing Skill  and a  Random Burst Skill. His base clear size is 15~18.

Strategy
Because Mater clears random Tsums, you don't need to let Tsums fall and settle before using his skill. This will save you time.

Trivia
Mater has a small TsumTsum plush toy coming out to the Disney Store in North America in June on this year. It's because the Cars 3 movie is coming out.
