What is caca marica?

Ca Ca Marica is a popular children's song in Inonesia and Malaysia in which the verses always start with "mana di mana" (english: where o where?) and then some nonsenscial fun follow-up about the location of an animal or other such thing that leads to the chorus: ca ca marica (hey hey!) ca ca marica (hey hey!) ca ca marica a da di kampung baru

as a singer of this song for many years, i was told by many people from both Indonesia and Malaysia that the actual Words "ca ca marica" don't mean anything - they are just nonsense Words that are fun to sing in a nonsensical fun song.
