Helen is the park ranger of Donut County. She sits up on a big wooden guard post keeping an eye out for snakes to capture to keep people safe. She is generally very laid back and carefree, besides the one thing that makes her very anxious, which ironically is snakes. She is pretty embarrassed by the fact that she has a job getting rid of snakes when they make her extremely anxious. 

For Helen's voice, I imagine a young adult female voice that is a bit higher than average. She is pretty carefree and not the smartest cookie so make sure to show that in her voice too. I also imagine her voice gets more high pitched when she gets embarrassed.
