There were several production and design changes that occurred on the TV show between season one and season two. Among them:

• Most episodes in season 1 were processed by using Film look, but in season 2, the episodes were filmized.
• The opening montage ends with a computer generated version of the interior of the Doodlebops' clubhouse. In season one a jib arm was used for a real shot of the room.
• Mr. Moosehead announces the name of the episode starting with season two. In season one, he would just say "Go Doodlebops" during the title card.
• The Doodlebops wore a Spandex hood that matched their makeup, with fake ears attached to make them appear more cartoon-like. In season two, the stick out style ears were removed, along with the hood.
• Deedee's bouffant hair style became slightly bigger, and more stylish between season one and two.
• Deedee's keytar is different and so is Rooney's guitar. Moe sometimes uses a portable version of his drums during the video.
• Two talking mannequin heads, who looked and sounded like a mocked up version of British royalty, were removed after season one.
• Occasional appearances from a chicken, a small alien, and other smaller creatures during the search for Moe no longer appeared after season 1.
• Moe frequently shrinks himself in order to hide from his fellow Doodlebops during the "Where's Moe?" sequence. In season one, Moe did not display his shrinking ability, opting to hide behind props, inside of boxes, etc.
• During season two, "The Pledge" has a longer introduction and a playful acrobatic sequence at the end.
• In season two, the featured song of the episode is performed by the Doodlebops in Audio Murphy's recording studio. In season one, the song is performed at Doodlebop Central (sometimes accompanied by Mazz).
• In season two, the Doodlebops manager, Jazzmin, is able to snap her fingers then disappear when she leaves, only to have the Doodlebops ask, "How does she do that?" at every occurrence. In season one, the manager was Mazz, who would exit the same way that she came in which was through a secret passage on the wall, while singing a jazzy scat style lyric. Jazzmin also does a slightly different jazz style lyrics than Mazz.
• Although not a very big change, the splash that hits Moe's head after he pulls the ropes is a much bigger splash in season two than in season one. Moe also grunts while shaking the water off and no longer utters “Refreshing” after getting splashed.
• After Moe pulls the rope, the Doodlebops head straight to their recording studio where they record and shoot the video for their upcoming concert with Audio Murphy. In season one, no recording studio was used and the Doodlebops would head outdoors to play and go about having fun.
• The "Get on the Bus" sequence underwent several changes from season one to season two. The bus itself was increased in size (from the outside), slight artistic alterations in the interior, the dance music was re-recorded adding in more instruments (such as horns or percussion); the Doodlebops no longer performed a "musical break" in the middle of the song.
• In season two, while on stage, each of the Doodlebops would have an article of clothing that is more sparkly than their usual everyday attire. However, when they are backstage and about to run onto the stage and start singing, they still have their casual costumes on. When the curtains go up, their concert outfits seem to have magically appeared on them when they ran onstage.
• In season one, during the concert segment the Doodlebops would perform two songs, sometimes three, or even four. Starting with season two, the concert was shortened to two songs maximum. In some episodes, only one song is performed.
• Deedee performs the "Knock Knock" joke in every episode with Mudge, and it takes place at a hot dog stand where Mudge is the hot dog attendant. In season one, this skit was performed in front of Deedee's mirror.
• The ending song is cut down in most episodes for timing reasons.

• Deedee's keyboard on the concert stage is now more like a benchtop.
• The "Knock Knock" joke goes back to taking place in front of the mirror, and has shifted the emphasis off the "knock-knock" variety. Also, the curtain doesn't come down during this segment anymore.
• The Doodlebops do the dance they did in Audio Murphy's studio again on stage. The dance is known as the Dance of the Day and is shown to the kids before the concert.
• To change into their tour jackets and their concert gear, the Doodlebops spin around. On the later costume change, they say "We're the Doodlebops!" while changing.
• The bookcase spins around instead of sliding outwards when Jazzmin comes in.
• The "Get on the Bus" song is sometimes cut down to save time.
• The background during the end credits is changed to one of the Doodlebops meeting and greeting their fans before the show.
