Annie is a member and the only survivor of the team that worked on the theme park, Anatomy Park, that was being constructed inside the body of a homeless man Ruben. She appears in the episode of the same name (Anatomy Park).

Annie was a member of Dr. Xenon Bloom's team and was apparently working at a churro stand in Anatomy Park.

You were inside the homeless man, exploring Anatomy Park as you meet Annie!
