If a person with my knowledge watches 'Trolls' movie & looks carefully at this Small Yellow Troll Girl - our conclusion will probably be the same! 

She wears a pink skirt & a ribbon & looks cute, like a girl...

- But her super strength, the Biggest Hair in All Troll Village & surprisingly Male Sounding Low Voice led me to a question: 'Could she have too much testosteron?' ( male hormon )

I think That would explain a lot! 

< & I will never forget How Much I was Laughing when I first heard her voice when she said 'OMG!' ... - I guess that was the 'Trolls' movie creators' goal: They wanted to make a Funny Contrast! 😂 - Because you see a small cute girl like her - but when she says something - She SOUNDS Like a Man! > 

< That's not the voice the viewers could previously expect! XD ... - I guess that before she spoke you were imagining her having a high girly voice, right? :D ... - I also thought so, but They Surprised Us! XD > 

*Btw: I KNEW that an actor who were voicing her Must have been a Man ( because no woman sounds like That! 😆  - & I was right: It was The same actor who voiced the Cloud Guy - I checked!  ^_~ ⛅👌 )
