Koen Bostoen would know the answer. The known resources on Vili are listed here. Kongo "goat" would be along the lines of nkombo and "lion" is nkosi, but there are many forms of Kongo: these are from Manyanga. As for "tiger" (also lion) there are no tigers in Africa or Curaçao (ignoring modern zoos), and no lions in Curaçao, so the source and current gloss are probably pretty approximate. Nothing within Bantu springs to mind, assuming a Kongo language source. Maybe tsjaca is "cat" (Bantu *paka), though the Manyanga word for "cat" is mbuuma. There is a word bubi "badness" which could be the source of bovi, though that's a stretch. Based on word length and known history, a Bantu source of the most likely source, but even then I would have expected more-recognizable words.
The most reasonable connection I can come up with is between sau and goat, via Germanic. English "sow", Dutch "zeug" and Norwegian "sau" have a common root, and interestingly Norwegian sau mean "sheep". I doubt there was any Norwegian influence on the language, but Dutch is more plausible.
If you have a reference (as in, where in the world did you get the data) or additional examples of the language, that would be useful information.
Given the data in the article linked by Yellow Sky, I would say it's not any form of Kongo. You might ask here: I don't find any matches on Gen, but that's not my area.
