In Operation: S.A.T.U.R.N., Numbuh 3 clearly tells Numbuh4 she smells Rainbow Monkeys with her heart, but in Operation: R.A.I.N.B.O.W.S. in season 1, she tells Mr. Mogul she sniffs Rainbow Monkeys with her nose.
In Operation: S.I.T.T.E.R., we see Numbuh Two holding out his pinky when he was with Cree. In Japanese traditions, holding out your pinky means girlfriend.
Saturn is a gas planet 1000 times larger than the Earth.It has a bright yellow atmosphere with brown clowds.In Operation: S.A.T.U.R.N. the giant world looked more like its neighbouring planet Jupiter.It had an orange-like atmosphere colour not, a yellow one.
Why did Numbuh 2 brush his teeth? Didn't Numbuh 1 say they should have dirty teeth in Operation: T.E.E.T.H.?
Note: Because Cree made him and Tommy do so under a threat she most certainly would carry out.
Scientific nitpick: Saturn is an enormous planet - if its rings were actually made out of stuffed toys, the amount of toys needed would more than triple the population of the Earth; so this episode is "wrong", seeing that the composition of the rings came from Earth.
(Talking about Rainbow Monkeys)
Numbuh 4: How can you smell them when there's no air in space?
Numbuh 3: I don't smell them with my nose...I smell them with my heart!!!
(In the ship)
Numbuh 4: Hey! The power is back on.
Numbuh 3: Ramon did it! Thank Ramone everybody!
The others: (Moaning) Thank you, Ramon.
Ramon 4: I am happy too, because I know you will stay with me... forever!
Numbuh 3: What are you, nuts?!
Ramon 4: Hey, you can't blame a guy for trying...
(Cree is about punch Hoagie)
The Tommy: Halt! Continue thy evil punch and face the wrathfully wrathful wrath of... The Tommy! (Lightning flashes)
Cree: Oh, give me a break.
Numbuh 2: You know, they say that taffy is an amnesiac.
Cree: THAT'S IT! It's time to put you brats to bed. For good!
The Tommy: But it's only seven o'clock! I don't wanna go to bed yet! You can't make me!
Numbuh 3: GET MY RAINBOW MONKEY!!
Numbuh 5: I don't think we can! It's traveling at Warp Factor Fast!
Numbuh 4: Why would I take something I think is stupid?!
Numbuh 3: You're jealous!! You could never spread love wherever you go! You're not made of a big rainbow! (Chokes him in a headlock)
Numbuh 4: (Sleep-talking) You like me too! Why didn't you tell me before? Well I think you're... (Wakes up to Numbuh 3 yelling)
Numbuh 2: Minty fresh, baby?! (Shoots Cree with toothpaste)
Ramon 4: (Telling Numbuh 3 about what happened) The scientists tried for many years to create a rainbow monkey in their own image. Unfortunately, they succeeded.
(After Ramon 4 finishes telling Kuki the story)
Numbuh 3: (Crying) A Rainbow Monkey not... loved? Oh, you poor, poor thing! (Hugs him)
Ramon 4: You would hug a monster like me?
Numbuh 3: Of course, silly! It doesn't matter what you look like on the outside! As long as you were manufactured by an official licensee of the Rainbow Monkey Corporation, I love you for the Rainbow Monkey inside!
(After Numbuh 3 hugs Ramon 4 again and the Rainbow Monkeys begin to sing)
Numbuh 4: Ugh... as if time to kill wasn't bad enough, now they're singing the cruddy song... (Bangs head on desk)
Cree: (Regarding her babysitting job) This is so not worth eight bucks an hour.
Operation: S.I.T.T.E.R. is a Numbuh 2 episode.
Operation: S.A.T.U.R.N. is a Numbuh 3 episode.
Apparently in the Codename: Kids Next Door universe the rings of Saturn are made of Rainbow Monkeys.
Eventhough the other members beside Numbuh2 appear for literally a second this is the third time a core KND member has had an episode where they appear alone. Numbuh1 had his in operation O.O.M.P.P.A.H., while Numbuh5 had hers in operation F.L.A.V.O.R.
We learn Numbuh1 likes Rainbow Monkeys because of the blue one under his pillow at the end of the episode.
Chad makes a brief cameo in Operation S.I.T.T.E.R.
Numbuh 2 believes (incorrectly) that taffy is an aphrodisiac. Truthfully, many people believe that chocolate, a more common ingrediant for fondue, is truly an aphrodisiac.
Numbuh 1's spacesuit is the same outfit he wore in "Operation: S.P.R.O.U.T." while inside Numbuh 4's body. These suits must be multifuctional.
Numbuh 4 shows that he's not as dumb as most people think he is. He was smart enough to point out that Numbuh 3 couldn't "literally" smell her Rainbow Monkeys because there's no air in space.
There was more possible Numbuh 3/4 proof in "Operation: S.A.T.U.R.N.". In his sleep, Numbuh 4 was talking to his pillow and gave out proof that he was happy that "someone" liked him back, after he told "someone" that he liked "someone" for a long time.
Villains: Cree & Ramon 4.
KND Technology: S.P.A.C.E.R.C.H.A.S.E.R.: Super Powered Accelerated Cruser Excellently Reaches Colassal Heights And Speedily Enhances Rescues.
"S.I.T.T.E.R." stands for Sweetheart's Involvement Transforms The Evening's Reality; "S.A.T.U.R.N." stands for Stuff Abducted Turns Up Revolving Nowhere.
Numbuh 3 once again displays her ability to track down Rainbow Monkeys like she did in "Operation: R.A.I.N.B.O.W.S.", but she reveals that the talent has nothing to do with her sense of smell (it comes from the heart, which kind of, well, figures).
"S.I.T.T.E.R." is the first "dream sequence" episode.
Credits: All the kids getting back their Rainbow Monkeys from Saturn, including Numbuh 1, who secretly hugs it, then hides it under his pillow before going to sleep.
Ramon 4 is really Rainbow Monkeys 4-Ever.
"S.I.T.T.E.R." is a Numbuh 2 episode. "S.A.T.U.R.N." is a team episode (more Numbuh 3-centric).
n/a: (Hoagie's bed comes to life and sprouts long legs)
When Hoagie's bed comes to life and sprouts long legs, it is
a reference to the animated movie Little Nemo's Adventures in Slumberland in which a bed also comes to life and sprouts long legs. The movie was mostly a dream sequence itself and was based on Windsor McCabe's Little Nemo's Adventures in Slumberland comic strip which was published roughly from 1905-1917.
Numbuh 5: It's traveling at Warp Factor Fast!
This is clearly a Star Trek reference. In Star Trek, faster-than-light speeds are measured by their Warp Factor, measured from the relatively slow Warp Factor One to the believed-impossible Warp Factor Ten (which is infinite speed).
Console: Sound Effect
When Numbuh 1 activates the manual drives of the S.P.A.C.E.R.C.H.A.S.E.R., the musical sound it makes is the same music that the UFO makes in the old Steven Spielberg film Close Encounters of the Third Kind.
Character: Ramon 4
Ramon 4 is a spin off of V-ger (Voyager) in Star Trek: The Motion Picture. In which (like Ramon) had letters rusted.
