On each round, you can find a doll. The dolls may be either visible or hidden (made visible by bumping into one of the rocks). Collect a doll and you will earn bonus points (amount equivalent to the Round Bonus) upon completion of the round.

Once collected, the doll for that round will be replaced by a hibiscus flower when you retry the same round.

If you collect all 36 dolls (nine areas, four rounds each), you will advance to the tenth area. If you don’t collect them all, the game will end at Area 9.
