DoorMouse is a recurring character in Team Umizoomi. He first appears in "The Butterfly Dance Show". He made his final appearance in "Umi Grand Prix". His theme sounds similar to the McDonald's commercial theme (ba da ba ba ba).

Physical Appearance

DoorMouse is a light brown mouse/rat with a medium build. Despite being a mouse, he does not have a tail to show it (The tail most likely tucked in his pants). He wears a blue jacket and pants, a light blue T-shirt, red sneakers, a yellow vest and a red stop-sign badge with a butterfly logo (most of the time). The stop-sign badge has various random symbols depending on the job.

In "Shark Car", DoorMouse has a different outfit consisting of a light blue sleeve-less shirt, blue swim shorts, and a whistle. He also goes barefoot. He retains the yellow vest and red stop sign badge though.

In "Shooting Star", DoorMouse retains most of his outfit except his own badge. He adds a belt, red cowboy boots, a blue bandana, and an orange cowboy hat. This same outfit appears in "Boardwalk Games", but with a yellow cowboy hat.

In the Umi Advent Calendar, DoorMouse is underneath the sixteen. He has a red jacket with white fuzzy lining and reddish sleeves and pants. His boots also have white fuzzy lining. He has a Santa hat and a green badge with possibly a bell on it.

In "Sledding Snow Day", DoorMouse's regular vest is replaced with a winter puffy vest, He also has a blue fuzzy winter hat.

In "Little Panda Joe", he has a yellow and blue checkered vest and a matching hat.


He is responsible for guarding and working on all doors, bridges, animals and anything you can think of that need a guard in Umi City, but that doesn't mean Team Umizoomi stops there. He does his job duties seriously, but always lets the Team though and sometimes helps them. Sometimes he mistakes other animals and things for what he's supposed to capture and save (in Ellee the Elephant, he mistook Ellee for a dog and in Shark Car, he mistook Shark Car for an actual shark). He was once a guard for a dog park where only poofy poodles were allowed to come in. Geo used his Shape Powers to disguise Bot as a poofy poodle, and Door Mouse thought that Bot was a poofy poodle.

He is helpful and friendly most of the time and is seen all the time with Team Umizoomi. Sometimes Team Umizoomi will help him, no matter if he needs it or not.

Sometimes, he doesn't help out, like in "Shark Car" when he trapped Shark Car and Team Umizoomi in the trap and didn't let them out. Also in "Haircut Hijnx," they had to trick him, so they could retrieve an an Umi-Dollar from the scenic area.

  • DoorMouse's role in Team Umizoomi may be almost similar to The Grumpy Old Troll from Dora The Explorer. The major differences are:
    • The Grumpy Old Troll is limited to just guard his own bridge. DoorMouse guards or watches almost anything.
    • The Grumpy Old Troll gives riddles and puzzles to hinder the person. DoorMouse doesn't usually do that.
  • DoorMouse is also similar to Eliot the worm in Third & Bird. They are both being the good friend to the three main characters. (Protagonists, their younger siblings and their best friends) For Eliot, they are Samuel, Muffin and Rudy, while for the DoorMouse, they are being Milli (counterpart to Samuel), Geo (counterpart to Muffin), and Bot (counterpart to Rudy).
  • As of the episode "Super Soap", DoorMouse has a different voice.
  • DoorMouse has the most appearances (Besides Team Umizoomi and UmiCar) out of any character.
  • DoorMouse has a major appearance in the episode "DoorMouse in Space".
  • In "DoorMouse in Space", DoorMouse says "You guys really are superheroes!", implying that he didn't think Team Umizoomi were superheroes before.
  • In some of the episodes, Geo expresses anger against DoorMouse. We don't know why he does that.
  • The DoorMouse never appeared with The Troublemakers until Umi Grand Prix! (Episode).
  • On the Boardwalk Games episode, that is the only episode DoorMouse talks to the home audience on the horse race scene with Milli.
