"Wally & Kuki sitting in a tree, K-I-S-S-I-N-G!" -Numbuh 2 & Numbuh 5 in Operation: B.E.A.C.H.

Hugging happy

how cute!


The Numbuh 3-Numbuh 4 Relationship is the most obvious, and possibly even the strongest romantic relationship in the show Codename: Kids Next Door. While Numbuh 3 does have a crush on Numbuh 4, he is more obvious about his feelings and that is shown in certain episodes, including Operation: B.E.A.C.H.. However, the two express their crush in very different ways: Numbuh 3 is very kind to Numbuh 4, while Numbuh 4 tries to act cool, using brashness and false bravado in order to conceal his feelings for her. This difference, though, shows that both of them are attracted to their opposite traits.


Wally Dreaming of Kuki (Operation N.U.G.G.E.T.)

Evidence of their budding relationship:
  • Numbuh 4 acts jealous towards other boys who flirt with Numbuh 3, including Ace "The Kid" (Operation: C.A.K.E.D.-F.O.U.R., Operation: R.E.C.E.S.S.) , King Sandy (Operation: B.E.A.C.H.), Numbuh 74.239 (Operation: P.L.A.N.E.T.), Numbuh 30c (Operation: A.R.C.T.I.C.), and even The Delightful Children (Operation: L.O.V.E.).
  • Numbuh 3, in her Citi-Zombie form, tells Numbuh 4 to kiss her, Numbuh 4 doesn't have to be asked twice, and they kiss twice when they become evil. (Operation: Z.E.R.O.)
  • Also in Operation: Z.E.R.O, Numbuh 3 and 4 almost kiss in human form but get interrupted by Numbuh 3's hamsters saving them.
  • Numbuh 3 had once forced Numbuh Four to wear giant butterfly costume, and become her costume assistant. She has also made him dress up as Mr. Huggikins and tell her that he loves her (Operation: C.A.T.S.).
  • She never acknowledges her feelings for Numbuh 4, yet she expresses it in several ways (for ex. hugging and acting nice towards him)
  • Numbuh 3 describes Numbuh 4 as an angry kid, having violent tendencies, hating hugs and liking bugs, but she still likes him anyway.
  • Numbuh 4 got mad and glared at Numbuh 74.239 as he put his arm around Numbuh 3 while he was explaining to them about what they might find in space.
  • They have each seen each other cry before, but Numbuh 3 has especially cried with Numbuh 4; and he has tried to cheer her up at times (for example, Operation: B.U.T.T.).

  • In Operation: H.O.S.P.I.T.A.L., Numbuh 4 becomes jealous when Numbuh 3 gets upset and emotional over an injured KND Operative, and when she tells Numbuh 4 that she loves the said operative, he is crushed. Numbuh 4 begins to confess his feelings for her, and Numbuh 3's has a big smile and her eyes become big and shiny because she senses this. However Numbuh 4 does not manage to finally tell her in the end, of course.
  • They shared the same bike during Operation: E.L.E.C.T.I.O.N.S..
  • They have danced together (Operation: D.A.T.E., Operation: P.A.R.T.Y.).
  • In Operation D.A.T.E. when Numbuh 4 couples up with Numbuh 3 by taking her hand Numbuh 3 is then seen hiding behind one of her sleeves or maybe hiding a blush.
  • In Operation P.A.R.T.Y. Numbuh 3 slow dances with Numbuh 4 who is making false disgusted faces but if you look closely enough you can see as they enter the kitchen Numbuh 4 is smiling at Numbuh 3 but then quickly changes back to being disgusted by saying 'Are you trying to kill me?!
  • Her favorite Rainbow Monkey is an orange one, a reference to Wally's orange colored sweatshirt. 
  • Numbuh 4 was forced to (or Kuki will start crying) help finish Kuki's final song in Operation: L.O.V.E., and sang "We're just the cutsie wootsie lootsiest pair". Then, as he stormed out of the theatre, Kuki cried, "We were just getting to the cute part! Come back! You're adorable!"
  • Dancing

    Also in Operation L.O.V.E., he breaks the set because he thinks that she is about to kiss the D.C.F.D.T.L.
  • There have been many instances where Wally has been interrupted from  lmost telling Numbuh 3 how much he loves her (for ex. Operation: U.N.D.E.R.C.O.V.E.R., Operation: L.O.V.E., Operation: H.O.S.P.I.T.A.L.).

  • In Operation: F.A.S.T.-F.O.O.D., when Numbuh 4 thought Numbuh 3 was eaten in a hamburger by sharks, he screams in horror and tragedy, "NUMBUH THREE!!!" And after that we see the rest of Sector V and a very angry axe whiling Number 4 running to the restaurant before noticing Numbuh 3 standing there until she said "Hi guys."

  • Numbuh 2 and Numbuh 5 made up the song "Wally & Kuki sitting in a tree, K-I-S-S-I-N-G" in Operation: B.E.A.C.H. (see above)
  • It has been subtly implied in a few episodes that Kuki has a great knowledge to the kinds of things Wally would and would not like [for ex. his favorite type of cookies (Operation: M.U.N.C.H.I.E.S.)]. 

    Numbuh 4 thanks Numbuh 3 for saving him.

  • They call each other by their real names more often than any other operatives.
  • They have saved each other countless times (for ex. Kuki saved Wally in Operation: E.N.D.), but Kuki has especially been the "damsel in distress" (for ex. Operation: G.H.O.S.T., Operation: B.E.A.C.H., Operation: G.R.O.W.-U.P., Operation: N.A.U.G.H.T.Y., Operation: E.N.D., Operation: C.O.U.C.H.).
  • Even though they hardly knew each other during their decommissioned  period in Operation E.N.D., they still flirted. 

    Numbuh 4 says "I love you".

  • They held hands when they adapted the boyfriend Helmet's explosion in Operation S.N.O.W.I.N.G. In addition Kuki became very angry, screamed, and pushed Wally when he exclaimed he will never tell a girl that he loves her.

    Christmas gift, and when she went back to her room, she cleared off all of her Rainbow Monkeys on top of her dresser to put his gift up there.
  • In No P In the OOL, Numbuh 3 did not have a signal; instead, Numbuh 4 went into her room and took her to the meeting.

  • In Operation: O.F.F.I.C.E., just when he was about to leave and let the girls be sent to Pluto, Numbuh 3 shows up and he does not leave without her. Also, when the rocket almost flew too far away from the building, he saves Numbuh 3, and not himself. Once she gets in the building, she tries to persuade Mr. Boss to land the rocket. Finally, when the ship does land, she runs over to Numbuh 4 and hugs him.
  • In Operation: L.I.C.E., Wally was the one to notice that the scream came from Kuki's room, and he is in front of the others when they all run to her.
  • Wally asked where Kuki was when he didn't see her in Operation: C.A.M.P.. Kuki also landed on Wally after the school bus ship crashed.

  • In Operation: F.U.T.U.R.E., Kuki was the one who knew instantly that future Numbuh 4 was telling the truth, and she she was the only one who cared that Numbah 4 was in trouble. In the beginning of that episode, Kuki said "You poor thing!" and "Send me a postcard!" to Wally when he announced that he had been sent to boarding school. Finally, at the end of the episode, he told present Numbuh 4, "...And most importantly, I always regretted never asking out...", but he disappeared before he could say "Kuki".

  • In Operation: N.A.U.G.H.T.Y., Kuki said she had saved the best gift for Wally, and she had waited in line for hours to get it.
  • In Operation: F.I.S.H.Y., a whole bunch of characters, including Numbuh 3, fell into the swirl pool, Wally only called out her name. 
  • At the end of Operation: K.A.S.T.L.E., when Numbuh 2 said King Sandy had a "weird taste in girls", not only did Numbuh 3 use a splanker on him (since King Sandy loved her first), but Numbuh 4 also did during the END TRANSMISSION. Numbuh 2 then asked, "Hey! What'd you hit me for?" To that, Numbuh 4 replied, "Nothin'..." The reason why he hit Numbuh 2 was because, since he liked Kuki, Numbuh 2 was then also saying that he had bad taste in girls, or just for the plain reason that he insulted Kuki
  • Numbuhs 2 and 5 either tell Numbuh 4 he has to tell Numbuh 3 he loves her, or they usually bother him about his crush (ex. Operation: B.E.A.C.H., Operation: N.A.U.G.H.T.Y., Operation: R.E.C.E.S.S., Operation: P.L.A.N.E.T.)

  • In Operation: Z.E.R.O., they held hands when they decided to go back to the treehouse to get Numbuh 2's device, and when they were about to be attacked by Citi-Zombie Numbuh 5. In addition, they held each other after Numbuh 4 put up the defense system.
  • In the Grim Adventures of the KND, Numbuh 3 and Numbuh 4 were the only ones to work right beside Mandy.
  • In Operation: C.A.K.E.D.-F.I.V.E., when Numbuh 4 stayed behind to get the Delightful Children's cake, Kuki was the last one to get inside the rocket with the rest of her team because she waved at him and said, "Good luck Wally!"
  • In Operation: H.O.M.E., when Kuki screamed, Wally was the first to drop his weapon and run to her. He was also in front of everyone else when they reached her, and he was the one to bend down, hold her, and ask her if she was okay.
  • They hugged in Operation: V.I.R.U.S.
  • It is revealed in Operation: I.N.T.E.R.V.I.E.W.S. that Numbuh 3 marries Numbuh 4.
  • In Operation P.L.A.N.E.T., when Wally was about to "confess", Kuki blushed and smiled, as if she knew what was coming.
  • In Operation N.A.U.G.H.T.Y., Numbuh 3 transformed back to her normal state when Numbuh 4 gave her his gift, tackled him in a hug, and said, "This is the sweetest gift you've ever got me! Well, it's the ONLY gift you've ever gotten me, but who's counting?" and Numbuh 4 blushes as he struggled to get away.
  • Wally seems like the guy who doesn't like to be bossed around but sometimes he will do things he doesn't want to do for Kuki like when he sang the duet from operation L.O.V.E and when he breaks Mr. Huggykins Wally dresses up like it to replace it in Operation C.A.T.S.
  • On operation B.E.A.C.H Wally is so focused on saving Kuki he forgets about Hoagie and Abigal

  •  In Operation: E.N.D., when Numbuh 86  informed the members of Sector V (minus Numbuh 1) that after decommissioning, they wouldn't remember their teammates or any of their adventures with the KND, Numbuh 3 and Numbuh 4 look at each other.
  • They held each other briefly in Operation M.U.N.C.H.I.E.S.
  • In T.A.P.I.O.C.A they are seen mocking Numbuh 2 together and giggling together about it.
