As of "Milli Saves The Day ", Milli is the only member to go on a mission alone. That is the only episode containing solo adventure and she is the only member who has done that to accomplish the objective.

"Milli" more literally means "by the thousandth" or just "thousand". It may also be based upon the word "chameleon" since she can change colors/patterns from her dress kind of like a real chameleon. Milli can also be a nickname of Millicent or Melissa, and an abbreviation for the term "per mille" (‰ ).

It's still possible that her full name could be one of those above.

Milli and Geo are the only main characters with canon ages, with Milli being six (6) years old and Geo being eight (8) years old.

They could also be of Japanese and/or Korean descent based on their background and the sound of their team name, Umizoomi, or the origin of the animated series, which resembles Korean culture.

For some reason, in some Team Umizoomi products, Milli's clothing has a more reddish tone.

Sometimes in the first two seasons, Milli's dress balloons out for a brief moment, allowing her to float momentarily. This serves as a homage to Walt Disney's 1951 animated film Alice in Wonderland. It is also a similar ability to Princess Peach from the Super Mario franchise.

In Haircut Hijinx , it is revealed that when she lets down her hair from her ponytails, she has very long red hair.

Out of all the members of Team Umizoomi, so far, Milli is the only member to not be in trouble. Bot was in Crazy Skates, Geo was in Milli Saves The Day while UmiCar was in The Great UmiCar Rescue .

Milli loves strawberry milk, as revealed in the episode The Milk Out .

Typically, Milli uses her Pattern Power to create inanimate objects that are missing in a pattern. However, in the episode Milli Saves The Day, Milli uses her Pattern Powers to complete a bridge of butterflies, creating three (3) butterflies in the process. This shows that she is able to create life as long as it is missing in a pattern.

Geo has this ability as well, but he can directly create life using shapes instead of being restricted to patterns, and does it more often in the series.

In several places, such as the captions for streaming services like Paramount Plus, Milli's name is often misspelled as "Millie".

She is the only character who helped the viewer count down from 5 to 1 during the Mighty Math Powers song.
