Busy, busy

Marlo gets very focused on her work in her Exersaucer. As she should. She is a Very Important Person with a lot of responsibility and not everyone can do her job. Which is why, when you interrupt her with your silly requests, she whips her head around and raises her eyebrows as if to say, with little patience, "Yes?"
When you're done with your nonsense, she gets right back to work. She hasn't got time for this.
