But that's a sly little goat in the video: she's not just complaining about something to herself. The cameraman tells her the English "What, what" - "What, what" in German - and the cute four-legged friend parrots it.
Over and over again the goat says that in an almost human way. And as you know, practice makes perfect, so the two-legged language sounds better from time to time with the little hoof-bearer.
