Top 10 Most Ridiculous Examples of Cartoon Logic

Minnie Mouse gets scared of a mouse

Well, she basically just looked back before her kind evolved. And maybe she saw that those mice were better, getting planets built for them and such.

Donald Duck never wears pants but is suddenly naked when shirtless

He doesn't like people seeing duck nipples.

He is a duck. Real ducks do not wear clothes.

SpongeBob takes a bath underwater

Nearly everything in SpongeBob SquarePants regrets nothing when it comes to cartoon logic. From this, to Sandy whistling or playing a saxophone with a glass dome on her head, to listening to music with eyes, to washing a sponge as a sponge, just everything.
Don't get me started on Mr. Krabs and Pearl being father and daughter.

The Three Little Pigs have their father hanging on the wall

You'd think that he'd go bad soon. They should either freeze him or eat him already.

They pulled a Euronymous and took a pic of his corpse. Now that's what I call dark.

It looks tasty, but I can't eat pork. Oof.

SpongeBob washes the dishes when he's a sponge

Not to mention that sponges found in the ocean are not the same thing as sponges found in a kitchen sink.

Mr. Krabs listens to music with his eyes

What are SpongeBob's sleeves attached to?

They were sewn to his tiny sponge arms shortly after he came into existence.

Gravity doesn't work until you look down

In that case, I'll just run around randomly and never look down.

To this day the "Uh-oh..." moment still makes me laugh.

I wish this was true, but sadly it isn't!

Dora can speak Spanish and English at age 4 but can't locate things right next to her

And she calls herself an explorer despite her choice to selectively travel through mapped territories.

Dora must be nearly blind because she needs the map to go around her room. But she's not fully blind.

Launchpad McQuack flies a plane when he's a bird

Flying is just too difficult. Like walking. Why walk if you can drive or use those electric scooter things?

Isn't he a duck too? Why don't any of the ducks like Donald fly?

?

Kenny from South Park dies several times but is just back again in the next episode with no explanation how it happened

It would be one thing if he had some kind of regenerative power, but instead he just comes back and you have to accept it.

?

In Courage the Cowardly Dog, Di Lung somehow always appears out of nowhere at the exact right time for his infamous "Watch where you're going, ya fool!" catchphrase

Arthur wears headphones but they're not on his ears

Well, that's how I use them. The rest of you are just doing it wrong.

Actually, aardvarks have enhanced hearing, so...

Maybe he has another invisible pair of ears.

Mr. Krabs's daughter is a whale despite him being a crab

My theory: He could've married a whale that died shortly after Pearl was born.

Donald, Huey, Louie, and Dewey eat a chicken

Does that mean that they are cannibals?

Damn, cannibalism in kids' cartoons.

How do Arthur Read's glasses stay on without nose or ear support?

Plot twist: Arthur's glasses are secretly goggles and they're tied up at the back of his head.

The Flintstones celebrate Christmas before Christ was born

Everything in SpongeBob's house is frozen except for the water

Jimmy Neutron goes to space without any helmet

That goes for a lot of cartoons where characters are in space and wear no helmet.

Why does SpongeBob live in a pineapple?

Goofy is a dog who can walk and talk, but Pluto acts like a regular dog

SpongeBob and Patrick have pants but Squidward doesn't

Ladybug and Cat Noir have bad superhero disguises, but no one, not even each other (except for a select few), knows their true identities

I've been waiting to talk about this. I haven't seen a single image on this, so I'm glad to write a large comment.
Sure, I haven't watched this show a lot, but I know a lot about it (I'll admit, I've read several wiki articles). The primary difference between both protagonists as superheroes and ordinary people is their personalities. Other than Chat Noir's night vision eyes, that's pretty much it.
No one knows who they are, even if many characters get a close-up look and picture of them. Not even the superheroes themselves know who they are, and they interact with each other every day! At least Tikki and Plagg know, and Plagg states, "People are blind." Everyone watching the show probably wanted to shout out to the characters in frustration, but at least we finally get to hear someone point something out.
Even Hawk Moth (spoilers), who doesn't look at them up close as much, suspects that Chat Noir is Adrien, and he's right. Honestly, even if we don't see the protagonists transform in the first episodes, we would already know it. It's so frustrating.

Brian Griffin has met Jesus Christ several times and is still an atheist

Characters are able to set fires underwater in SpongeBob SquarePants

Is Mr. Boss holding his cigar with his nose?

He probably stuck the cigar up his nose.

Cartoon characters survive major injuries that would cause death in real life

You can get your head blown off, your whole body can explode, and you can fall 420 meters to the ground and not die.
