Sara Simple

Sara Simple is a deuteragonist, a daughter of Mrs. Simple and Mr. Simple, a granddaughter of Mrs. Simple's mother and a daughter-in-law of Mayor Tinkerton and Mrs. Tinkerton in the animated film; The Legend of Frosty the Snowman. She is a sharp and independent young girl, who is Tommy's love interest and dreams of becoming an urban planner instead of a princess when she grows up. At the beginning, she doesn't know the first thing about "captivating to a suitor" (which was meaning for "true love") or discovering the truth about the history of Tommy's father; Mayor Tinkerton.

Also, she did not first like Tommy before (strongly believing that he is under Principal Pankley's control), but however, until when she looks through the Frosty the Snowman comic book (that Tommy had found in the secret room underneath the public library), she apologizes to him for her actions and decided to join him and the crew afterwards to help rescue Frosty, who had melted through the thin ice.

In the epilogue, while reading an "Urban Design" book, Sara gave up on her dream and decided to be with Tommy, since she now likes him, instead. Her voice will be portrayed by Emma and Sara will be a very-well behaved young girl in GoAnimate (Vyond) World.
