How exactly the baby talk works. Can baby talk be typical baby babbling or do the babies actually talk but they choose not to speak to or in front of the adults, further proof of this is they only seem to communicate when the adults leave the room like in the pilot. In “Angelica’s Birthday” they also informed her that babies aren’t supposed to talk to adults but never explained why. It seems like the baby talk is understandable by beings with a lower level of brain function. Younger children can understand them, but so can adults who've suffered a head injury and regressed to a baby-like state (seen twice with Stu and Nigel Thornberry). Animals also seem to understand babies at least as well as they understand adults, as a parrot could imitate Tommy's speech in "The Case of the Missing Rugrat" and Spike seems to understand Tommy as well as he understands Stu and Didi, if not better.
Was Tommy the heroic, assertive and fearless leader of the babies or a reckless Designated Hero and Manipulative Bastard comparable to Angelica who coerces his friends (particularly Chuckie) into doing what he thinks they should do based on his perceptions and getting his way? A little of both? The episodes "Farewell, My Friend", "Garage Sale" and "The Odd Couple" showcase the theory of him being more than a little Innocently Insensitive (such as continually painting Chuckie's interests as "weird" and being an overall lousy houseguest or giving away all of his parents' belongings to their immense chagrin, particularly Stu's).
Similarly such episodes also totter as to whether Phil and Lil were good if occasionally weak willed friends to Tommy and Chuckie, or merely neutral brats who could be easily influenced, even having times they sold out the other babies to Angelica when she coaxed them with good things rather than bullying them. Their cowardice, while maybe more reserved than Chuckie's, could arguably also be seen as more prevailing, as shown in cases like "Farewell, My Friend" where they gladly left Tommy to his fate, which Chuckie found he could never live with doing (eg. "Dust Bunnies" or The Movie).
Many fans view Angelica as The Sociopath based on her Troubling Unchildlike Behavior as seen in "The Trial" as well as her out of nowhere freakout in "The Box" and it's assumed that her Freudian Excuse is that her parents are somewhat negligent towards her and clueless about her that it probably kinda warped her and, as a result, she gets a strange kick out of telling lies to her cousin and his friends and she has no idea how to be a good friend.
To go along with that, other fans believe Angelica is a neglected and lonely kid who, not fully aware of her own Freudian Excuse, takes out her sadness and frustration on the babies. Episodes in which she's nice to or protective of Tommy and friends, such as "New Kid in Town" and "Moving Away" lend support. There's also the fact that in "Runaway Angelica", her response to Drew disciplining her for the first time is to run away from home and then she fears he's actually happy she's gone. And in "Mommy's Little Assets", when Charlotte is disciplining her, Angelica tearfully asks if she's going to be fired.
In "Angelica's Worst Nightmare", Charlotte tells Angelica that she's having another child, and Charlotte and Drew are both thrilled. In the end however, Charlotte tells her, while sounding rather sad, that they're no longer having a baby. Naturally, she didn't give her 3-year-old daughter any details, so just what happened has stumped fans for decades. Was it a miscarriage, or just an inaccurate and disappointing test result?note It should be noted that, while home pregnancy tests *can* be wrong, when they are, it's almost always a false negative — false positives are VERY rare.
Assuming "Chuckie's Wonderful Life" is All Just a Dream, Chuckie can be painted as a Small Name, Big Ego who convinces himself that the whole world would fall apart at the seams if not for his constant direction. Alternatively this along with other episodes like "The Odd Couple" might suggest he suffers from OCD, a known psychological element to the disorder is believing terrible things will happen if you do not commit to things in an exact way.
Another episode involves Tommy, Chuckie, Angelica, and their parents attending a wedding. While most of the guests are happy for Tommy's Uncle Ben and his bride Elaine, Chuckie's father Chas is shown crying his eyes out. Could it just show how sensitive he is, or is it because he's thinking about his own wedding to Melinda? The fact that Hulu's captions describe his crying as "weeping" may lean towards the latter explanation.
Was Drew really a traumatising Big Brother Bully to Stu as a kid, or is Stu just an Annoying Younger Sibling with a victim complex and a massive Self-Serving Memory? This even ties into the aforementioned example with Tommy, since the one unbiased flashback of them as kids ("Sour Pickles") shows Stu to basically be a Generation Xerox of Tommy, and Drew basically Chuckie but more assertive to the former's brattiness. Is Chuckie being an Extreme Doormat the only thing preventing him and Tommy being constantly at each other throats?
Was Miss Carol fired at the end of "Word of the Day" not necessarily for cursing on live television, but because she physically screamed at a three-year-old who got tongue-tied and then ordered the child off the stage when she said a curse word? It's also possible that her attitude was so poor that the higher-ups may have been looking for any chance to get rid of her.
In "Slumber Party", was Tommy having a nightmare, or was he awake but hallucinating?
In "Chuckie vs. the Potty", Chuckie mentions that his mother putting him on the bottle was the worst thing that ever happened to him. Is this just because he preferred being nursed to using the bottle (perhaps for no reason other than his already-established fear of new things)? Or, since "Mother's Day" later reveals that she's dead, did she put him on the bottle because she knew she was dying, and he hates it since he associates it with her death?
Was Josh from "The New Kid in Town" actually a Manipulative Bastard, or was he just trying to skirt the rules his parents imposed on him by doing mean things that are technically "fair" according to what he knows about fairness?
Is Ranger Frank Drinking on Duty? Perhaps that would explain his excessive freak-out at seeing a dragon.
Given the events of Rugrats Go Wild! confirming Rugrats is the same universe as The Wild Thornberrys, the animals are therefore confirmed to be sapient. In the matter of Scar Snout the Wolf, his being sapient indicates that a very likely way of interpreting his character is that of a sadistic Serial Killer who knows he's targetinghuman babies. If not that, then as a desperate, hungry animal who just can't help but see the babies as quick, easy prey and just a regular animal hunting normally. The former is more clearly apparent though due to the demeanor Scar Snout displays throughout his scenes mostly being hostile and predatory along with what looks like a gleeful disposition down to him also looking like he's cackling as he is nearly upon them.
Did Angelica's shouting really cause Didi to go into labour? Or, seeing as Tommy was also a preemie, is she just more likely to give birth early?
Coco doesn't sound facetious when she mutters under her breath that she "must have [the heart of a child] in a jar somewhere". That implies heavily that she's at one point had at least one kid killed and collected their body parts—or at least collected the parts even without killing or having anyone killed. It's not hard to imagine she's done it for multiple people either—or given Coco's earlier comment as well about telling Jean-Claude to make sure no fingerprints were left behind, to have done other insanely criminal things too.
