Pazu's original line in the movie stated that he wanted to see the place where Sheeta was born; here he says he wants to see Sheeta in the same state (of undress) that she was born in. The school swimsuit fetish is another creative liberty.
I want to see it...
The same way you were when you were born, the valley, your Yaks, and your school swimsuit.When this is all over I'll take you back to Gondoa...
