The most unique display came though at the very end. We almost left already, when a dancer group from Tonga appeared. They presented a truly exotic folklore and customs. We never saw before a genuine Tonga dance performance! Some dancers were... covered in oil, and one female dancer received numerous dollar bills stuck to her body and costume. People keep throwing money at her, literally(!), and later a group of "keiki's" collected the numerous bills scattered on the dancing stage. We were very curious if this is a real Tonga Islander custom, or just a special event?
