Annie is a kind and sweet 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 the youngest and the smallest of the group, she has blonde hair with pigtails bounded by pink bows. She has beautiful blue eyes and a smiling mouth. Her skin tone is fair. She wears a green shirt with a blue jean dress and magenta and white shoes.
But in Season 2 her outfit changed: her shirt is light blue instead of green, her jean dress is pink instead of blue and her shoes are blue instead of magenta and white.
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. Also, she made meet-and-greets with people, just like the other Little Einsteins except Rocket.
- She was the only character who has piloted Rocket solo.
- 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.
- The color of her jean dress changes from blue to pink in Season 2.
- 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).
- The color of her shirt changes from green to light blue in Season 2.
- 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.
