This is the first time that the major Disney characters have regularly appeared on television in computer-animated form. They Might Be Giants also perform the song used at the end of every episode, "Hot Dog!", which echoes Mickey's first spoken words in the 1929 short The Karnival Kid.

The show features two original songs performed by American alternative rock band They Might Be Giants, including the opening theme song, in which a variant of a Mickey Mouse Club chant ("Meeska Mooska Mickey Mouse!") is used to summon the Clubhouse. For example, in "Mickey's Silly Problem", when the "Silly switch" turned on, Mickey for some reason, spoke in rhymes for half of the episode. By calling "Oh, Toodles!" Mickey summons him to pop up from where he is hiding and fly up to the screen so the viewer can pick which tool Mickey needs for the current situation. Once the tools have been shown to Mickey on the Mousekedoer screen, they are quickly downloaded to Toodles, a small, Mickey-head-shaped flying extension of the Mousekedoer. Another one is a "Mouseke-Think-About-It Tool" represented by a silhouette of Mickey's head with rotating gears, in which characters must think of what to use before telling the Tool "Mouseke-Think-About-It-Tool, we pick the (object)".

One of them is a "Mystery Mouseketool" represented by a question mark, in which, when the words "Mystery Mouseketool" are said, the question mark changes into the Mouseketool the viewer gets to use. Once the problem of the episode has been explained, Mickey invites the viewers to join him at the Mousekedoer, a giant Mickey-head-shaped computer whose main function is to distribute the day's Mouseketools, a collection of objects needed to solve the day's problem, to Mickey. Mickey, Minnie, Donald, Daisy, Goofy, and Pluto interact with the viewer to stimulate problem solving during each episode's story.
