"Jeepers, Creepers, Where Is Peepers" is the first part of the 12th episode of season 3 of Dexter’s Laboratory, which aired on July 12, 2002. In the episode, Peepers, the ruler of Dee Dee's imaginary world Koosland, gets kidnapped, and as a result, the place gets destroyed by a villain named Hookocho. Dexter and Koosy must save him.
First off, the villain's design comes off as kind of inappropriate since his catsuit has a gold codpiece. It does not help that the catsuit is tight-fitting and is almost the same color as his skin, giving the illusion that he is naked since his skin is an extremely pale blue color and his catsuit is white with a gold breastpiece. His design is also extremely out of place, due to him designed in anime style, which greatly contrasts the series' more "blocky" art style reminiscent of early Hanna-Barbera television cartoons of the 1950s-1960s.
Peepers' character design, at least before the mutation, looks incredibly cheap and ugly as he looks nothing like a dog despite being conceived as a dog.
It also tries to be disturbing for no reason, with the infamous scene in which Peepers gets graphically mutated into a dragon.
There was an inappropriate moment where Koosy tells Dee Dee the backstory where Peepers creates Dee Dee's imagination as a baby but it shows that her imagination was made of sperm with hearts on it.
The episode also has one poop joke in which a laser gun Dexter is holding gets turned into poop by the villain.
There are many plot holes that have yet to be explained. For instance, where did Hookocho come from and why did he want to destroy Koosland?
Dee Dee's role is minor, as she's the only one who didn't go with Dexter and Koosy to Koosland and she stays in the laboratory.
If there was a backstory and a reason about Hookocho's existence and why he wanted to destroy Koosland, the episode would come off as decent. Same goes if the infamous mutation scene was cut.
The scene where Dexter is moved by Koosy's sympathy for Peepers and all other creatures in Dee Dee's imagination feels rather forced.
The Only Redeeming Quality
Although inappropriate and out of place, the villain's design looks cool.
The villain's name is often misspelled, e.g. "Hokochu", "Hokochoo", etc.
Hookocho is meant to be a parody of effeminate anime characters.
The title is a reference to the 1938 song Jeepers Creepers, whose first lines of the refrain are "Jeepers Creepers, where'd ya get those peepers?". The song was featured in the movie Going Places released in the same here, where it is performed by jazz musician Louis Armstrong. However, the song is most famous for being the main theme of The Creeper, the main antagonist in the 2001 horror film Jeepers Creepers.
