Here is Twilight Sparkle and Sunset Shimmer, as jungle girls, doing the Tarzan yell together by a waterfall.
In case you are wondering… No, Sunset is not taller than Twilight. She’s just standing closer to the edge. I sort of imagined this scenario to be that since Sunset has lived as a human for longer than Twilight, she would be the expert on how to use hands, and therefore, she took here on the task of teaching Twilight how to beat her chest properly, as a human would… And at the same time, teach Twilight the cool Tarzan yell, which Sunset has heard in some old movies.
