How did Bowser get his Black Magic at the end of Season 2 of Mario and Luigi's Stupid and Dumb Adventures? We see Craig the Devil in later episodes starting from September 2014, so he could have made a deal to get these powers from him.
In "Jeffy's Birthday!", when Jeffy soils himself, Mario heads off to change him, only to notice a torn letter in Jeffy's pants. Jeffy believes he pooped out a letter, and when Mario asks him about the rest of the letter, he tries to poop out the remaining bits. If you look closely, you can actually notice Jeffy did not poop out a letter, but rather had it in his pocket, probably from when he was first dropped off at Mario's door.
In "Jeffy's Mistake!", Mario's first choice for babysitting Jeffy is Shrek, noting that both like poop, but then one remembers that Shrek has a son, so out of all of Mario's friends Shrek may have more experience taking care of a child, making him a suitable babysitter for Jeffy.
Which could have actually happened if it weren't for him making "biochemical warfare" with his crap for the duration of the entire day. Also, Shrek's son had already ended up being non-canon by the time of the video.
Shrek later actually babysits Jeffy, along with Junior, in "Shrek The Babysitter!", only to lock them in the bathroom after they eat his cheesecake.
There's actually a clever hint that shows Jeffy is probably not as stupid as he looks, among many others. In "The Dog Show!", he swears about all the things that essentially make him stupid, a clear Call-Back to "Jeffy's Homework!".
Also, in the same episode, why did Brooklyn T. Guy allow Joseph's dead dog, but not Jackie Chu's cooked dog or Jeffy's hot dog? Joseph is a kid and his dog most likely died from starvation and he didn't let go of him or know he was dead, but Jackie Chu is an adult, Jeffy is also a kid, and they know mostly well that, in Jeffy's case, his dog is a hot dog, and in Jackie Chu's case, he cooked his dog.
Why did Brooklyn T. Guy act like the body parts in the food and apple bobbing tank at Freddy Fazbear's Pizza were normal in "Bowser Junior's 8th Birthday!"? In the games, they cover up everything to stop themselves from going out of business, and Logan just either made it the opposite or Bowdlerised that.
In recent videos, Junior's spoiled brat traits have slowly died down significantly, and he's far more empathetic towards others than he was before. Then you remember that Logan does a video once a year focusing on his birthday, and Junior is growing more mature with age as he gets older every year.
Not just that, but if you go back and re-watch some of Logan's older Junior videos, you'll notice that Junior nowadays has a much deeper voice than he had compared to earlier videos where he usually sounded a lot whinier, even if he wasn't upset.
In "Jeffy's Bad Word!", Jeffy is traumatized and terrified after Mario spanks him. As a result, he ends up making Mario's life, and in turn a lot of fans' lives, a living hell. With the reveal that he came from an abusive prostitute smoking alcoholic mother, it makes sense why Jeffy would be so traumatized after getting spanked.
Jeffy is a lot nicer to Junior than he is around most other characters, to the point where Junior could be considered his closest friend. He relates to Junior not only because they are both morons, but because they both had to deal with beatings from their parentsnote Although Bowser is a more loving parent than Jeffy's mom could ever hope to be.
Why is Jeffy a potty mouth, and why does he sometimes put his "pee-pee" in several objects, despite being a young kid? Considering who his mother is, he may have learned several swear words from her and since she's a prostitute, he may have seen stuff he would've not seen at such a young age.
After his mom gets arrested, Jeffy gets adopted by Mario. Wouldn't it be just to permanently live with Mario in the first place? He even promised to be a good boy, yet keeps annoying Mario following his adoption.
In some videos Brooklyn T. Guy is seen as a burglar, despite the fact in other videos he's seen working on the side of the law. Does Brooklyn have a secret that his teammates at the police don't know, or is Does Bad Things Guy the one in the videos where Brooklyn is portrayed as a burglar?
Not to mention Brooklyn T. Guy, while he does arrest some actually dangerous people like Nancy, he's not at all a competent cop. At best, he'd suspect you and do regular check ups ("The Dead Body!"), but at worse, all it takes for someone to just punch him or joke about his wife and he'll just leave the house, so it's hard to believe Goodman wouldn't know Brooklyn Guy's weaknesses given his connections.
Also, while Junior was a witness, it doesn't guarantee that he'll be believed if he calls the police again since he's known to be naughty and isn't above lying not to mention he tends to call 911 for stupid reasons or has even prank-called them. Best case scenario, he'd likely be dismissed as a liar byBrooklyn Guy and maybe even the other adult characters (such as Bowser and Chef Pee Pee). As for Brooklyn, he'd more than likely be frustrated at having to come back to the house and look for Joseph's mom again and that's without covering his general incompetence or even his lack of patience for children.
In a lot of episodes, Cody would make references to being breast-feed by his mom. Of course, by typical viewing, this is seen as an example of his perverted side, but when you consider Cody was born on a leaf-day, which makes him technically two years old by the time one of these comments was made, perhaps his nutrient is also that of an infant.
Why does Goodman trust Mario with valuable objects even after they get misplaced only to be retrieved at the last minute? It might not actually be stupidity on Goodman's part. He makes his usual threats of violence and mutilation if he loses them, so he likely knows Mario could fail just so he has an excuseto mistreat his employee.
How is it that Mario is never able to pay his house payment on time? Well, considering all the things that tend to get destroyed or broken in the house on a practically constant basis, it's likely he doesn't have the finances necessary to keep up with that and paying Goodman.
Each Playtime video begins with him entering the scene while Joseph is cooking dinner, which soon devolves into him berating and abusing the latter. It's likely that Junior saw this attitude whenever Bowser would to the same thing to Chef Pee Pee.
Playtime Junior is rather prone to getting pissed off easily, not too different from his father lashing out over seemingly trivial stuff.
Joseph:
According to him, his mother would be abused by her alcoholic husband, which explains his role as the housewife who gets the Butt-Monkey treatment by Junior, who fittingly gets alcohol problems to go along with Joseph's dad's attitude.
Cody:
Both Junior and Joseph have had their other parent absent through most of their lifenote though Joseph's father wasn't as absent as Junior's mom, but considering Joseph's account of him being an alcoholic, he may have had more time to spend passed out on the couch than with his own son, meaning that they would naturally play the role of the parent that was present, leaving Cody, who has both, to play the child.
In "Jeffy's Sister Returns!" Jeffy has a dream in which Feebee returns to the house to annoy Mario, who incessantly assures Jeffy that Feebee "is not real". Later on in the episode, Jeffy reveals to the real Mario that Feebee is his dead sister, but is convinced that she's just "sleeping in the ground". Could a part of Jeffy be aware that Feebee is actually dead, and dream Mario is just his subconscious urging him to dismiss the traumatic event as a figment of his imagination?
From what's implied, Jeffy is aware that she's gone and, for the most part, in denial (the "sleeping in the ground" bit, supposing that Nancy didn't tell him this), so the Dream Mario is most likely his subconscious repressing the memories more so than what he already did (he hasn't brought her up outside of saying he's had dreams about her).
In the Alternate Universe in season 3 of Mario and Luigi's Stupid and Dumb Adventures, Mama Luigi is revealed to be smart and Mario is implied to be the stupid one, so this means that in that universe, Mario will probably die soon.
In "Home Alone", three robbers infiltrate the house, but Junior kills two of them and tries to kill the third one. While they were robbers, Junior didn't know and thought they were his babysitters. So if Junior had actual babysitters, he would think it would be funny to murder them.
If that's his reaction to babysitters, it begs the question if he has murdered previous babysitters before or what kind of babysitters he's had before to give him that reaction.
In "Joseph's House!", the fact that Joseph hasn't moved out the corpse of his mother and he keeps it on the place she died, leaving it to decompose into a skeleton.
And in this episode we find out that Boos are exactly the same as canon, begging the question: What will King Boo be like when he appears in Luigi's Mansion?
In "The New House!", Brooklyn T. Guy reveals that 26 people died in the new house, tries to be on his calmest when doing so and completely forbids the gang to open the door inside an empty room for God knows what else. When you think about it, you get shivers just wondering what the house originally came to be, especially when you see the Funny Background Event wherein Brooklyn tries to shut the door as a LIVING SKELETON tries to get in.
This, and his underlying behavior in the episode, may probably suggest that Brooklyn may be just as insane as Joseph, if not more.
Also Fridge Brilliance, but in "Broken", if you look closely on Ken in the scenes before he falls from the balcony and breaks in half, he could be most likely trying to get out from the balcony when Junior and his friends weren't looking. Was Ken committing suicide?
In "Bowser Junior's Playtime 5" Junior's method of dealing with a crying baby is cook it in the microwave. It makes you thankful that Junior couldn't get any girls like Emily, Samantha, Britknee, etc., because not only would he grow to hate them later in life, but also because he would ruin any chances of having kids if the simple act of a baby crying makes him do that.
Though it is Nightmare Retardant in a way, because Junior was actually a pretty loving, if incredibly stupid, father in "Chef Pee Pee's Kids" when he and Cody were looking after Junior Jr. and Chaz.
As of "Sicken", rape may not be the only crime Cody could ever do. In fact, he got pushed far enough to the point where he became straight-up homicidaljust because Junior broke Ken. Not to mention that the victims-to-be would've been Chef Pee Pee, Bowser and Joseph, which makes it doubly vile as they are characters he has had the hots for (and in the case of Bowser, also had sex with twice) and one of his friends respectively. If breaking a doll is enough to provoke Cody into attempted murder, who knows what else will?
At the end of "The Dead Body!", it is revealed that Mario didn't kill Hansel and that he was simply unconscious. Had he not woken up at all, Jeffy would've killed Hansel for real with his buzzsaw.
Furthermore, people who die in the series often come back, which means that despite being shot in the head, Does Bad Things Guy could come back and resume his evil, murderous ways.
While one may say that Does Bad Things Guy was just a one-off character. Brooklyn showed rather unprofessional behavior in "Stuck!"—not only did he make fun of Chef Pee Pee for being raped by Mrs. Nutkiss, but he also gives into her advances, implying he may be still around.
Speaking of Joseph, it is also implied that he may have killed animals for food. This includes a cow (which he somehow managed to salvage a heart out of), as well as fish and squirrels. Now, if you consider the amount of time he's been living alone and subsequently been insane, it can't be really hard to imagine how much animals Joseph has slayed. Worse yet is when you consider the fact that he manages to get away with mass animal slaughter.
Just a meta Fridge Horror, if Logan kills off Jeffy, what happens to the show? Does that mean that SML will be over?!
In "Jeffy's Drivers License!", it's revealed that BrooklynT. Guyisn't above accepting bribes from criminals. He's been shown to be quite a useless cop in many episodes before, but that leads you to wonder... has he done this sort of thing before and if so, then how many criminals have gotten away scot-free? Even worse, how many people lost their livelihoods because of this?
In "Bowser Junior's Girlfriend", Judy develops a crush on Bowser Junior after she turnsinto a kid. She's been shown to be a rather perverted woman before but this episode seems to reveal she can also have pedophilic tendencies. When you consider that she has cheated on Tyrone in some episodes and even violated Chef Pee in "Stuck!", that raises the question: has she romanced (let alone had sex with) other children before, afterward or would she?
Jackie Chu apparently got a PhD in Calculus, but according to himself, he can barely see and his vision is so bad that he draws a bunch of scribbles when trying to write his own name. Kind of a miracle that he was able to master Calculus in the first place, isn't it?
Jeffy wants to live with Mario because Nancy hits him and only brought him back for his father's fortune, yet Mario hits him just as much and also adopted him for the same reason. In a way, Mario is not so different from Nancy, yet Jeffy ends up living with Mario.
In most cases, Jeffy successfully gets revenge on Mario for hitting him (such as in "Jeffy's Bad Word!").
Mario only spanks Jeffy as punishment for misbehaving (such as swearing or breaking things) or repeatedly annoying Mario until he loses his temper. Nancy, on the other hand, doesn't want to care for Jeffy and hits him for, among other things, seeking help that she should give him, but doesn't want to.
Goodman constantly forces Mario to give him his house payments, which isn't so bad at first, but in "The Bet!", he also makes Mario pay to wash his car. Goodman is supposed to be a billionaire; could he seriously not afford a car wash?
Yes, he could do that but it's possible that, otherwise, he doesn't really have any friends (it has been shown in some episodes that they can be civil with each other).
Even after "The New House!", Bowser continues to treat Chef Pee Pee horribly. But Mario is the primary breadwinner who technically owns the house and wouldn't be above evicting his housemates if they angered him enough (see "The Couch!"). So it should be easy for Chef Pee Pee to inform Mario of the abuse and for the latter to threaten to or just straight up kick Bowser out of the house.
Why exactly does Mario trust Jeffy with an endeavor like driving his car to school when it's been shown hundreds of times beforehand that he can't even trust Jeffy to do something as mundane as cleaning the dishes?
, he has also managed to collect a "ball jar", and has implied that balls (and to a lesser extent nipples) are rare delicacies to him. This becomes even darker when you think about how much people he has tortured as punishment for missing house payments — and as a result would've left physical and psychological trauma on them — as well as the fact that Goodman never looks back on how his victims may have felt or experienced. Like Joseph's mother, he gets away with it.
