Dee Dee's Room is the first part of the 6th episode of season 1 in Dexter's Laboratory, which first aired on June 2, 1996. In this episode, Dee Dee steals one of Dexter's inventions, forcing him to go into her room to retrieve it. While doing so, Dexter tries his best to avoid the Cooties.
Dexter treks into Dee Dee's room to find an invention that she stole.
Dexter's most recent invention goes missing when tries looking for it. After some deducing, he's certain that it's inside Dee Dee's room -- a room he's never been in before, nor ever planned to be in. Now, he needs to go in and retrieve his invention without getting any cooties.
The walls in Dee Dee's bedroom are pink, but in the episode Changes, it was revealed that they were teal with yellow flowers on them. Starting with this episode onward, her room is pink.
The Bubble Gum Tape Dexter used to trap the cooties momentarily, is a direct reference to the extremely popular real life bubble gum brand Bubble Tape. The gum was extremely popular during the 90's and was a favorite among kids and adults,the gum usually contained six feet of gum tape at the time.
After Dee Dee kisses Dexter and his face breaks out, he begins to say 3 times in a dramatic parodic way "The horror, the horror, the horror...." this culturally references Kurtz famous last whispering words "The Horror! The Horror!!!" from the movie 1979 Apocalypse Now before he embraced his death.
An only appearance of a man Dexter described as Dr. Gray is shown observing charts of anatomy.
