Well, she's actually pretending to be a monster - she's voicing the lead character in the Myrna The Monster cartoon about an alien coming to terms with growing into adulthood:
“I think just that [Myrna]’s so awkward and she seems kind of like, you know she really wants to be a part of things but doesn’t really know how,” Hanna says. She also says she can relate deeply to Myrna on that level. “I’ve always been a person who like, I make friends by doing projects. If I need friends, I start a basketball team or a band, some kind of project that involves other people. I don’t really know how to just straight-up make a friend, you know what I mean? I’ve always felt socially awkward.”Not entirely sure how successful you could be at forming a basketball team while being socially awkward, but you get the point.
