Mandark, Dexter's longtime rival, broke into his lab and attempts to destroy it by reprogramming Computer to make sure Dexter can't enter. It works, and Dexter, unable to enter without the correct password, heads to Dee Dee's room and get his voice-modulating invention.


Taking place in both Dexter's house and his laboratory, the game is divided into four levels, each with challenges featuring Dexter's various inventions. Each level contains two minigames that the player must complete in order to progress.

There are eight minigames in total, both of which can be played for one or two players.


  • Dee Dee's Dance Off: A Dance Dance Revolution-styled minigame where players compete with Dee Dee to score the most points.
  • Cootie Call: A first-person shooter-styled minigame where players are tasked with spraying the Cooties that appear in Dee Dee's room. Dexter moves around automatically. The name is a pun on the phrase "duty call".
  • What's Buggin' Dexter?: Players must chase and swat five bugs.
  • Up and Atom: Players must collect cores while warding off rogue atoms. The name is a pun on the phrase "Up and at 'em".
  • Soap Box Derby: Based on the episode Mock 5, players must beat Mandark in a 5-lap race around the track, using power-ups to stop him along the way.
  • Dexter Dodgeball: Based on the episode of the same name, players must strike the other kids with dodgeballs.
  • Molecular Mix-Off: Similarly to "Dee Dee's Dance Off", players must press the buttons in time to the music to copy Mandark's chemical mixing moves.
  • Sub Zero Hero: While competing against Mandark, players must be the first to score five goals.

Atlanta Journal-Constitution's Troy Oxford praised the minigames, making the title a success.

PSIllustrated's Stephen Triche praised the game's graphics, but was displeased with the game as a whole and labeled the minigames as "dull." He also stated; "I get the feeling Red-Lemon Studios used a young target audience as an excuse for making a game that I've quite simply found lacking."
