Hang on, I'll save you the trouble: No they aren't Botocudo but........
Both excellent films, Como era gostoso is one of my faves. They re-released it on DVD in Brazil a couple of years ago. If you can find it I'd also recommend Brava Gente Brasiliera which deals with indigenous resistance in the late 18th C. Great scene where after lulling the fort's garrison with an offer of women, the Indians storm the fort. Like Hans Staden it's based, quite closely on a true story.
