* AccidentalAesop: While not pointed out, the movie teaches a lesson on how you shouldn't try to marry someone you don't know that much. Chaz knew Coco for less than a month and he didn't know how horrible Coco was until the wedding day.
* BreakawayPopHit: The Baha Men's "Who Let the Dogs Out?", to a certain extent.
* CrossesTheLineTwice: Spike peeing on a wall? Gross. But then that wall turns out to be ''THE EIFFEL TOWER''.
* CrowningMusicOfAwesome: [[spoiler:When Chaz and Kira get married.]]
** [[https://www.youtube.com/watch?v=aTAjY9xlXQo The Chuckie Chan theme]].
* EvenBetterSequel: One of the main complaints about the first movie was the lack of focus (other than Dil and Tommy's changing relationship) and no real antagonist. This one addresses both by giving the lead to Chuckie and a much more relatable story for both parents and children. As well as making Coco a worthy villain for the film to focus on.
* HeartwarmingInHindsight: This film marked Creator/ChristineCavanaugh's final performance as Chuckie before her retirement, and seeing how the plot is so focused on him that it's been nicknamed "The Chuckie Movie," it can be seen as a celebratory send-off to his original actress.
* ItWasHisSled: [[spoiler: Chaz marries Kira, and Kimi becomes part of the Rugrats]].
* MoralEventHorizon:
** Jean-Claude pilots the Robo-Snail mecha against the babies' Reptar mecha and attempts to destroy it, knowing full-well the babies are inside and even ''gleefully'' going along with it.
** Coco was pretty much unpleasant throughout the film, but she [[KickTheDog wrenched Chuckie's]] TragicKeepsake [[KickTheDog out of his hands and then ordered Kira to destroy it]]. [[EvenEvilHasStandards Even Angelica looked shocked!]]
-->'''Coco''': [[KillItWithFire Burn this moth eaten plaything!]] [[EvilIsPetty I never want to see it again]].
** This is also when Kira realizes that Coco does not care about either Chaz or Chuckie.
* {{Sequelitis}}: Averted. This film is said to be better than the original. See EvenBetterSequel above.
* SignatureScene: "I Want A Mom" is perhaps the most memorable moment in the film for any Rugrats fan. The big climax between the babies and Jean-Claude and the wedding of Chaz and Kira also stand worthy of mention.
* ToyShip: As this is Kimi's introduction, this is also where shipping her with Tommy got started, particularly from the scene where they're watching the stage show and Kira places Kimi in Tommy's seat with him.
* WhatAnIdiot: Unsurprisingly, the adults all have their moments of this. Coco LaBouche's comes when she lies about having a new husband and child simply to impress her departing boss, which kicks off the main part of the plot. Chaz's comes from attempting to marry a woman who he did not know and who had all the characteristics of ObviouslyEvil, cementing him as a HorribleJudgeOfCharacter before recognizing his mistake. Finally, ''all'' of the parents for being irresponsible enough to leave their children in the care of Jean-Claude, another individual who they hardly knew and entrusted to bring to the wedding without issue. Compounding their lethal stupidity is not immediately rushing out to find their missing children upon realizing that they were nowhere to be found, instead carrying on with the ceremony.
