One of the episodes that have a lot of "sex related" stuff is The Baby Project! which is that Jackie Chu is teaching the students about having sex and in the chalk board they drew a picture of a naked woman and you could clearly see its nudity even though it's just a drawing.

In SML Movie: Jeffy's Trap, Rosalina states "I'm not wearing any underwear" to her boyfriend Mario. Implying she is planning on having sex with him.

In SML Movie: Jeffy's Bedtime, Mario and Rosalina want to put Jeffy to bed to they can have 'Adult Alone Time', Implying sex. Jeffy continues to interrupt them and Mario yells at him to 'quit cockblocking' him.

In SML Movie: Friday the 13th, The boys are seen watching Hey Arnold on Nickelodeon. After Helga calls Arnold 'Football Head', Arnold states that 'his head isn't the only thing shaped like a football. He then proceeds to bend Helga over and mimics sex.

In SML Movie: Jeffy The Rapper, Jeffy claims that while he was in prison, he 'got his Pee-pee pierced'. Not only that, but the fact that 'they messed up a few times so his pee-pee looks like a flute'.

Many episodes have references to Cody being gay, and other things like that. His boyfriend is a Ken doll.

In "SML Movie: Chef Pee Pee The Octopus" there are many sexual jokes made

Jeffy tends to smack his diaper

Puppet Nudity

In a lot of episodes they talk about "sex related" things and also have sexual humor in their videos.

SML Movie: The Secret Door features large amounts of violence. Showing over 20 puppets who had been severely killed and dismembered. Brooklyn Guy chains up our protagonists and knocks them each out with hammers. The video ends with Brooklyn Guy getting shot in the head and killed.

Characters are constantly getting hurt and harmed. Most commonly Mario. For Example, in Rosalina's Ex-Boyfriend, Mario keeps trying to beat D-Money in a fight and continues to get beaten until he's bloody.

In the episode 'Zombie Bowser' a TV programme shows a bloody zombie puppet with an eye gouged out

In one episode, Mario accidentally runs over a homeless person with his car, panics and stuffs it in the boot of the car. Jeffy then puts the body below a circular saw and it is implied that he sawed the corpse in half because we see him later on with blood on his shirt however at the end, it is revealed that Jeffy only sawed a ketchup bottle in half and the homeless man is alive

In Jeffry's Tantrum, Jeffry attempts to hang himself.

SML:The Gun has lots of blood.Cody gets shot in the eye.Junior cuts his hand off because he touched the gun leaving fingerprints all over it.He cuts Chef Pee Pee's hand too because he touched the gun ,as well.

In the episode "Pop Rocks And Coke" Chef Pee Pee takes a challenge from Bowser Junior, Chef Pee Pee puts pop rocks in his mouth and then drinks coke, causing his head to explode.

A character named Doofy The Dragon often commits suicide.

The drone is one of the bloodiest episodes of the entire show, Junior gets his tongue sliced out and chef pee pee loses an eyeball. Both of these scenes are quite bloody

In The Episode "Toad's Mistake" Mario And Luigi Torture Toad, Severely Damaging Him Physically And Mentally, This Includes Clubbing Him In The Head With A Baseball Bat, Throwing Him In A Basketball Hoop, And Drawing On His Face?

In Junior's 8th Birthday, they order pizza and Joseph has pizza with eyes and body parts. It's not too graphic.

In one episode black yoshi shoots a newscaster and the newscasters head explodes with blood and you can see his brains ooze out and the his visible skull!

Jeffy literally tries to commit suicide and Bowser Jr also has "fun" hanging himself.

Bowser violently beat Jr over his broken cup

There isn't much violence in SML but some episodes have very brutal content. In a few episodes characters die with bloody results and most notably in "Chef Pee Pee Quits Part 5" there are severed limbs. There is some violence such as punching, kicking, beating up.

In SML Movie: Jeffy the Rapper, there are quite a few uses of The-N-Word and many more uses of other racial slurs including: Cracker and Vanilla Biscuit.

"Fuck" is used a lot in each video.

Jeffy is infamous for his foul-mouth during his rampages.

Although the word "Cunt" is never used in actual videos, in SML Movie: Jeffy's BAD Christmas, one of the closed captions (submitted by a fan) says "Finally, a break from that cunt." which describes the writer's hatred to Jeffy.

For a brief period between December 2017 until March 2018, some videos lacked swearing due to the channel's demonetization, but it fully returned when Logan moved new uploads to his SuperLuigiLogan account. From July 2019 until 2021 due to the Cease and Desist, a majority of videos on SuperBowserlogan lacked profanity, but with the full transition to the puppets videos and rebranding to SML, videos have gotten back to having swearing again, although not as frequent as before.

The swearing is pretty bad some of the SML videos are age restricted on youtube.

Most of the bad language is said by one person (Jeffy)

Almost every character has sworn at least once in the series. Jeffy and Goodman are the biggest abusers at this, followed on with Cody and Chef Pee Pee, and to a lesser degree Mario himself. Bowser Junior, Joseph, Rosalina and Black Yoshi swear more infrequently, or less frequently than the other characters.

Jeffy once flipped off Teacher Chu in the video, "Jeffry's Medical Problem."

Mild words such as "Hell", "Damn, "Bitch", "Ass", "Bastard", and "Douche" are regularly used in videos. Stronger words occasionally used. TV-MA profanities such as "Fuck", "Shit", "Goddamn", and "Asshole" are bleeped out on some versions and unbleeped on other versions. The channel in 2017 is uncensored.

Many drug references throughout the series.

Root beer is compared to Alcohol since it has the word beer in it. In Bowser Jr's playtime, Junior plays an alcoholic father who constantly argues with his wife, played by Joseph

Jeffy frequently shouts "Are you fucking high?!" at Mario.

In the episode Bowser Jrs' sleepover Doofy the Dragon says "Make sure to do cocaine kids!" Meant for laughs.

Drug references in some episodes but that's about it. Doofy is seen snorting cocaine in "Bowser Jr.'s Midnight Snack".

In SML Movie: Jeffy's New Toy, Jeffy buys a scary looking doll with black eyes. Later on in the episode, the power goes out and unsettling music begins to play. Mario finds 'LIAR' written in blood on a table and then Rosalina throws the doll in front of Mario and the camera, it is a jumpscare. It is then revealed that the whole thing was a prank from the beginning,also there is another jumpscare at the end of the episode.

Dark humor is quite frequent.

In the episode Jeffy Skips School, the math problems stereotype Chinese names "Ching Chong, Ping Pong, Sum Dum Ho, etc

Bowser Jr and Jeffy's teacher is a stereotyped Asian

"Bowser Jr.'s Sleepover", "Cody's Sleepover", "Bowser Jr.'s 8th Birthday", "The Secret Door", Chef Pee Pee Quits Part 5", And "Jeffy's New Toy" Might Be too Scary for young children.
