Ruthie is the young farm girl who befriends Big Bird in Follow That Bird. Along with her brother Floyd, Ruthie offers Big Bird shelter in their barn and introduces him to the joys of farm chores through the song "Easy Goin' Day". The friendship is interrupted by the abrupt arrival of Miss Finch. Her mom and dad don't appear in the movie but her mom's voice is heard off screen telling her and Floyd that it's time to go to bed.
Ruthie's singing vocals were dubbed on "Easy Goin' Day" by Pam Rose.
