The shape of bum-bums are seen on various characters, but there is no real nudity (Remember, this is still a kids show). Doesn't get much worse than that.
Some comic nudity.
Subtle innuendos are there but it's rare.

Mild fantasy violence is usually used as self defence against terrifying beasts and certain characters.
In some episodes there is moderate violence rarely you can see GORE.
Even most of the violence present in this cartoon is mild and it's mostly towards fantasy characters (think of punches, kicks, swordfights... and the consequent bruises and scratches), in some cases this can be a little more graphic and even include red blood and gore, but that's rare.
The series mainly takes place in a post-apocalyptic world. The opening has a dismembered arm inside a hollow tree. Very fast, can't be seen without pausing. Fans think the arm belongs to Shoko.
In "The Enchiridion", Finn kills a monster shaped as a heart, red blood sprouts all over. Very brief and the blood might have not stained anything.
Some decapitation of small parts (noses and hands), or limb removal, mauling (i.e. arms chopped off) throughout the series, but no blood, only flesh wounds.
Several fight scenes are played out for humor. For example, there is a character named Ash, who everyone hates, since he is a douche. Marceline kicks his crotch and Finn starts beating him up with her. Finally Jake stomps him with his giant foot. Even the Ice King (Simon Petrikov) in one episode punches him with no good reason.
In "Who Would Win", Finn and Jake start beating up each other, because they are proving themselves who is more resilient. Both of them have lots of nasty looking bruises and cuts.
In "Freak City", the Magic Man turns a bird inside out making it show the birds guts, flesh and everything else.
Some scatological humor, including spitting and visible green vomit in some episodes, when the characters are disgusted. For example, Jake explicitly vomits into a jacuzzi in the episode "Jake the Dog". Farting is more frequent.

There are not actual swearing but sometimes they use euphemisms.

Emotionally intense scenes when the show refers to character's backstories.
In one episode, Magic Man opens a door by constantly cracking and breaking his wrist.
Some characters have scary faces or bodies. Some are just disturbing in general.
Mild/Moderate in a lot of episodes.
Mild/Moderate for neurodivergent viewers.
The tone varies from light hearted and fun, to very dark and disturbing and at times can be very unsettling and uncomfortable to watch, for the majority of the show it is light hearted but it has those episodes and moments that are very dark and disturbing.
For older kids/tweens and up.
Sometimes in episodes things go from good to ominous and dark, but what is unique is that it is interpreted as thrilling and not offensive in those scenes.
Characters can get tense and yell at each other sometimes.
Lemongrab eats Lemongrab 2 once and is next time seen with a chunk of his face bit off and he has no torso. Lemongrab 2 is eaten again and is seen again inside the stomach of Fat Lemongrab with a larger chunk of his face bit off.
