Sven

Sven is a Premium Box Tsum Tsum.

Information
Sven is a Horizontal Burst Tsum Tsum. His base Skill range is SS in the Japanese version and XS in the International version. Although it is not specified at first like it is for other Tsum Tsum, his base number of Tsum Tsum required to fill his Skill meter is 15. Higher Skill levels reduce the number required. The minimum number required (at max Skill level) is 10.

Strategy
Make sure they are no Bubbles left unpopped in Sven's path, so that Sven can clear more Tsum Tsum.
