Story and Plot
Dexter's rival, Mandark, has broken into Dexter's laboratory and is attempting to destroy it by reprogramming the lab's Computer to block Dexter from entering. This works, and Dexter is unable to enter without the right password and has to mimic Mandark's voice. After retrieving his voice-modulating invention from DeeDee's cootie-ridden room, he has to dance with her in order to convince her to guess the password. Acquiring it, he successfully gets into the lab.
Finding that nothing in his lab responds to him now, he has to clear the computer systems of rogue atoms and get rid of a cyber bug that is destroying the system from the inside. Eventually he finds Mandark, who uses an early invention of Dexter's (an age-changing device) to turn Dexter into an old man. Though hindered, he is able to recharge the machine after first powering it through reliving memories.
Turned back into his normal age, he finds Mandark again, discovering that he has set a bomb to go off to destroy Dexter's large fish tank, filled with salt water that will destroy the lab. DeeDee, having followed closely, suggests a game of wills against the two, bribing Mandark to play by promising to kiss him; if Mandark loses, he must give up the code that will deactivate the bomb. Losing to Dexter in both a chemistry experiment and ice hockey, Mandark gives a moot code in response. However, Dexter had seen through it and has successfully deactivated the bomb, saving the lab. Defeated, Mandark leaves, vowing revenge. Though all seems well, DeeDee angers Dexter by trashing one of his equipments.
Based on the television series, the game is set in both Dexter's house and laboratory.
