That's usually the case, but you can see in some other lines for other characters there's little issues with the lines posted, like, for bully 1 it says: "says hey let's get out of here", but you can kind of infer that the casting director is not hoping to have someone actually say the the "says" part. Likewise, just based on the creatures look, I don't think they're going for it to be a sort of weird almost meta monster who actually says "making a hissing a growl noise". I just personally can't see that as coming off as anything serious, and that's the type of character I think this is going for. Though, I don't work on this project, and like I said, you could be looking at this in a way I just never would naturally, and that could very well be exactly what they're looking for. It just feels out of place based on all of the story and other characters I've seen so far. Just my opinions, and sorry if I offended you, I do seriously like your voice type here though.
