Sawsaw-Suka

 
The name literally translates to "dip into vinegar." The "it" has his palm open while the other players touch this with their index fingers, singing "sawsaw suka/ mahuli taya!" which translates to "dip into the vinegar/the last one (or the caught one) becomes "it". And indeed, the "it" tries to catch any player's finger at the end of the song.
