She mostly wears a dress and a helmet, tight stockings and Mary-Jane shoes. The outfit's default color is pink and the dress and helmet have a pattern of pink flowers. The outfit changes color and pattern (See Milli's Many Patterns). Sometimes when someone or Milli mentions her dress, she curtsies for fun. She has definite age to be 6 years old, according to the website.

In Movie Madness!, she has only one ponytail in some of the movies.


  • Milli-Measure: Milli's pigtails, but she prefers "ponytails", become a ruler, scale, Etc. She can also use it to add measurements to specific things, which was revealed in one of their promos.
  • Pattern Power: In episodes up to "The Big Boat Race", Pattern Power is, basically, applying a pattern onto an item. In episodes starting with "The Dinosaur Museum Mishap", Milli changes her dress into a pattern mostly to add somthing missing to the pattern by peeling the picture of the item off with that picture fading then more color added, to fix a pattern or to follow a pattern to get through obstacles. Examples of her dress patterns are on Milli's Many Patterns.
  • Ponytails: Milli's hair extends to her liking. See more on Milli-Measure.
  • Karate: Milli knows how to do karate. She has powerful chop, kick, even her ponytails. She mostly uses her skills to get past pattern and remove measurements or to divide something into fractions.



Milli is really sweet, cute, and generous, but don't let her cute looks and sweetness fool you. She is also fearless, strong, and would do anything to help and save her friends. That's why she's the leader of Team Umizoomi. She's also the strongest member of the team.

Even though Milli really loves and cares for her brother Geo, she sometimes doesn't have faith in him with his ideas at first.

Personal Life

Revealed in The Kitty Rescue, Milli has a pet bunny named Whispers. In Umi Toy Store, Milli revealed to have some experience in playing the toy piano. Her favorite food is her Pattern Sandwiches.

Milli is known as the animal-lover on the team. She just can't stand the sight of baby animals so much, that she can jump for joy. Her love for animals make her a great rider of animals. From horses, to dinosaur, to even dragons, Milli is not scared to ride any animals, and she always asked before getting on animals.

In Milli saves the day, she reveals her true brave side by going to the mission alone.
