King Julien mentioned the dancing baboons in the episode "Assault and Batteries".
Darla: Now I'm gonna say this slow cause I can tell ya'll got a bad case of the stupids.
Julien: Maurice, how did she the royal medical report?
Darla: Ya'll are gonna apologize, or my gals and I are gonna make us a set of lemur coats!
Mort: OHHHHH! Can I have one?
(Maurice whispers in Mort's ear)
Mort: ... I cancel my order.
(Skipper accidentally got Julien's groove)
Skipper: Fix this.
Julien: I don't know how.
Darla: Guess who does.
Mort: Is it Santa?
Darla: Ye... WHAT? NO! I'm the only one who can fix this. But am I gonna?
Mort: Santa would.
Darla: WELL I AIN'T SANTA!
Character debut: Darla the baboon.
Title: "Out Of The Groove"
The title could be a play on the 1985 song "Get into the Groove", by Madonna.
When Skipper has King Julian's "groove" in his body and he starts dancing, he does the moonwalk at one point.
The moonwalk was invented by Michael Jackson.
