What does "シュパシュパー" mean?


I struggle looking up onomatopoeia, I tried, but the closest I found "dry,"
but in context, it makes no sense.

Context: わーい！ あたしも司くんも、シュパシュパーって 忍者さんみたいに動くよ！




It describes a swift and sharp movement, exactly like our image of a ninja. If
you could find nothing with シュパシュパ, perhaps you can try image search for
"シュパパパ" instead, which is an even quicker variant of this.
