Annie is a sweet and adventurous little girl. She cares deeply for her friends. Just like the rest of the team, she is caring and friendly. She loves to sing and is very good at it.
Annie is a small female girl, the smallest of the group. She has blonde messy hair put into pigtails with pink butterfly bows. She wears a sleeveless blue jean dress (pink in Season 2) and a green undershirt (light blue in Season 2). She wears a pair of purple and pink converse styled shoes (blue shoes and white socks in Season 2). Her dress is usually accompanied by a front solo pocket and stitches down the side.
Little Einsteins is the only media she has appeared in. Annie has appeared in every episode.
She made an appearance at Walt Disney World as a puppet in Disney Junior - Live on Stage! in Disney's Hollywood Studios Theme Park and Animation Courtyard. She also made meet-and-greets with guests, just like the other Little Einsteins, save for Rocket.
- She was the only character who has piloted Rocket by herself.
- She loves animals, but she is afraid of spiders, just like the rest of the team (as seen in Our
BigHuge Adventure), except for the one in "The Treasure Behind the Little Red Door" and the one in "Rocket the Bug". It is also shown in Our BigHuge Adventure that she is afraid of bats.
- She loves dolphins as proven in Pirates Treasure, but her favorite animal of all is a horse as seen in "The Great Schubert's Guessing Game".
- She owns a silver microphone with orange music notes that she won in a song contest.
- When she wishes to urgently point something out to the team, her usual catchphrase is "Look, look, look!"
- She might have arachnophobia (fear of spiders).
- In Season 2, the color of her shirt changes from green to light blue and the color of her jean dress changes from blue to pink.
- When she is really happy, her smile gets bigger.
- In Rocket's Firebird Rescue, Annie was given Music Power, and may now have it permanently.
- She loves animals just as much as she loves singing.
- She always sings her special good-night song to herself at bedtime, as mentioned in A Galactic Goodnight.
- All though she is the only singer of the group; she can be found singing along with June.
