Just look around on a few of the more recent threads. There are links to them. 
Yes actual kids! Jessie Flower would be awesome for Wilykit, but then the A:TLA comparisons and references would never stop.
I’d also like new talent.
I’d just like to point out that just because we mention the voice actress for Toph doesn’t mean we want or even believe that Wilykit will behave or act like Toph. They’re actors. They can do more than one type of voice and more than one type of personality.
Perhaps Jessie Powers will be asked to do a voice in the new Airbender cartoon.
Exactly. What I’m saying is, if she were to be cast as Wilykit. Keep in mind, she can use a different vocal range. It just really depends on how her character is portrayed and the direction and this instance, the voice direction is given by Andrea Romano.
I said what I said by keeping in mind some of her other performances, she still sounds like Toph.
Either way. As long as the performance delivers, who cares who does the voice.
Well, that too, I agree with that.
I’m thinking AnnaSophia Robb might be a good choice for Wilykit.
Interesting choice, she can act.
Having heard them in the leaked footage they sound really young (sorta Toph-ish) and both the twins sound very similar to each other but they dont sound exactly the same.
