Dexter vs. Santa's Claws is the third part of the 37th episode of season 2 in Dexter's Laboratory. It first aired on April 29, 1998. In this episode, Dexter tries to convince Dee Dee that Santa Claus doesn't exist.
Dexter wants to prove to Dee Dee that Santa Claus doesn't exist, so he sets up a monitoring system on the roof. A man in red finally shows up and when he enters the living room, Dexter tries to take a picture to prove that it's just his Dad in a Santa costume. When Santa resists, Dexter decides that more drastic measures must be taken, taking the chase from the bedroom to the rooftop to the skies.
Dee Dee: Those better not be my presents!
Dexter: Hold still, father!
Dad: Dexter, what are you doing?
Dexter: Shut it! Hold still! Ha, ha! I'm almost [stops and turns around]
Dad: Dexter, what have you done?
Mom And Just Look At Us Christmas Tree How Dexter.
Dee Dee: Where the heck are my presents?
Dad: Dexter, what do you have to say for yourself?
Dee Dee: Hi, Santa!
Dexter: Come back here, Dad!
Dee Dee: Dexter? DEXTER!!!!
Dee Dee: You Block Head That's Not What Christmas is About.
A brief parody of A Charlie Brown Christmas occurs after Dexter defeats Santa.
Dee Dee takes the microphone from Dexter during his rap. But, in the next scene, the mic on her hand disappears.
Throughout the episode, the number of reindeer changed. When we see them on the computer screen, there are only two. When they were on the roof, there was only one, and when Dexter was chasing Santa, there are eight of them.
This episode was received negatively by fans, mostly because of Dexter's treatment to Santa Claus.
This episode contradicts the events of "The Beard to be Feared" where Dexter himself met Christmas Elves and went to the North Pole. A possible explanation is that this episode takes place before "The Beard to be Feared" canonically.
This episode was featured on the The Powerpuff Girls: 'Twas The Fight Before Christmas VHS/DVD and on the Cartoon Network: Christmas Rocks DVD from 2007.
