BB-8 rolls across the screen clearing all the Tsum Tsum on the bottom of the screen. His base Skill range is SS in the Japanese version and XS in the International version.
Ensure the bottom of the screen is filled up with Tsum Tsum before activating Skill. Tap all Bubbles before activation (to increase Tsum Tsum count by 1 or 2).
