Dexter and Computress Get Mandark! is the first segment of the thirty-fourth episode in season 2 of Dexter's Laboratory. It first aired on April 29, 1998.

This episode is notable for being written by Tyler Samuel Lee, a then 6½ year old boy who was a fan of Dexter's Laboratory and submitted his own fan story based on the series on an audio cassette, to which the producers like so much and set it to animation and aired as an actual episode.

In this episode, Computress, Mandark's robot "brother", ditches Mandark and his laboratory after watching him wreck it one too many times and getting tired of having to fix his messes. He then teams up with Dexter to get revenge on Mandark.


Dexter is in his laboratory working on his inventions, whereas at Mandark's house, Computress, Mandark's "brother", is working on repairing everything that Mandark broke. When finished, Mandark kicks Computress to the curb.

At Dexter's laboratory, he and Computress both come up with a plan to help the latter get back at Mandark for being banished from his lab. They then get to work on making a shrink ray to reduce Mandark's head size. Just as Dee Dee enters the lab, Dexter zaps her with a mind control beam, causing her to walk out of the lab.

Computress then forges a love note to Dee Dee from Mandark while Dexter does the same thing, but with a note to Mandark from Dee Dee. Computress puts Mandark's "letter" into an envelope and hands it to the mail truck driver while Dexter puts Dee Dee's "letter" into a chute and ships it to Mandark's laboratory. When Mandark opens his envelope, he becomes lovestruck and races over to Dexter's house while Dee Dee throws her message in the trash.

While watching from a monitor, Dexter and Computress put their plan into action by running over to the shrink ray, which they aim at Mandark just as he runs into the laboratory and kisses the invention, thinking it's Dee Dee. As Mandark runs around with a shrunken head, Dexter and Computress both fall out laughing. However, Computress bumps the lever on the shrink ray with his rear, causing it to fire a beam at Mandark to make his head grow to immense proportions.

Angered, Dexter goes to berate Computress for his mistake while Mandark prepares to act on his secret plans. Once more, Computress activates the "Grow" function on the shrink ray, making Mandark's head enlarge even more until it explodes. A barrage of Mandark heads come out of Mandark himself and rain down on the planet. Dexter again chastises Computress for his fatal mistake, causing Computress to walk off with his head lowered.


Speaking roles[]

Non-speaking roles[]



  • In the online game Cartoon Network Universe: Fusion Fall, Dexter's Computer is renamed Computress. Whether this was a subtle nod to the episode or not is unknown. Unlike in the show, Computress in the game was characterized as a female robot voiced by Hadley Puntereri.

Production Notes[]

  • Tyler Samuel Lee provided the voices of Dexter, Mandark, and the Narrator in this episode, rather than Christine Cavanaugh and Eddie Deezen.
  • This is a very rare example of a cartoon episode in recorded history that was ever entirely scripted by a fan of a TV show. It was based on an audio cassette that Lee sent to Cartoon Network, which was then set to animation. Usually, for legal reasons, fan-created submissions are not allowed.
    • The only other times something like this happened were when Tiny Toon Adventures had an episode written by three teenage girls that were fans of the show and submitted their story to Warner Bros. Animation ("Buster and Babs Go Hawaiian"), and when The Ren & Stimpy Show had an episode adapted from a comic a young fan made about the show and sent to Nickelodeon ("The Cat That Laid the Golden Hairball").
  • Tyler's mother could be heard in the background.
  • When Tyler's mother prompted him, she quickly appeared on the lower third of the screen.
  • Another notable example of the literal adaptation comes when Tyler, transitioning to the next scene, narrated "...and then Dexter said..." without finishing his statement. The animation showed Dexter beginning to talk, but saying nothing and having a startled look on his face.
  • This episode alongside with "The Justice Friends: Pain in the Mouth" and "Dexter vs. Santa's Claws" were produced in the same year of 1998 according to the credits.
