This happens to be on SpongeBob's list of the most fun things he likes to do.
"Oh, that kinda hurts. Come on! Ooh, that really hurts! Oh, barnacles, this hurts! (hyperventilates) Conch-shelled manatees, THIS IS PAINFUUUL!!!"
— SpongeBob, "The Splinter"
Yes, this "kid's show" has enough Family-Unfriendly Violence to give it its own page.
- In "Mermaid Man and Barnacle Boy IV", SpongeBob shoots Squidward with Mermaid Man's belt, making him undergo painful transformations. Among them, getting set on fire, losing all skin, and getting cut in half. Later, SpongeBob shrinks every single citizen of Bikini Bottom. They get their revenge on him by invading his body — he has holes everywhere, so invading wasn't much of a problem for them — and crushing him from the inside. This includes breaking his bones, destroying his kidney, punching out his eyes and brain, and one fish almost sawed a blood vessel in half... Yes, it did look creepy and painful.
- In "To Love a Patty", SpongeBob kills a flock of scallops with his bare hands to protect his beloved Krabby Patty. At one point, you can see one of the tongues flying out.
- "Plankton's Regular", when Plankton rips off his own skin and a later scene where SpongeBob has his front skin peeled off by Nat opening the Chum Bucket door.
- "Atlantis Squarepantis" has SpongeBob and Patrick's flesh melt off of fear.
- In "Dying for Pie", SpongeBob performs open heart surgery on Squidward, and accidentally cuts his heart, with lots of blood spraying from it.
- "House Fancy" has probably the most infamous example of this: the scene with the leg of a couch ripping Squidward's toenail off.
- In "Enchanted Tiki Dreams" at the beginning, SpongeBob and Patrick are caught up in their game they created and Patrick jumps on Squidward's head breaking his neck, and SpongeBob steps on his barely intact neck causing his head to fall off, though seconds later he picks it up and screws it back on.
- In "Karate Star", Patrick cuts his own hand off. Justified since he's a starfish and can regrow limbs.
- In "Sand Castles In The Sand", Patrick briefly tears off his skin while imitating SpongeBob tearing off his clothes reveling his swimming trunks.
- "Squid On Strike" has Squidward tear SpongeBob in two, and you can see his bones and organs.
- "Roller Cowards" has SpongeBob and Patrick Buried Alive.
- In "Doing Time", Mrs. Puff angrily rips a guard's face off.
- "Restraining SpongeBob" has Squidward fried alive.
- "Walking the Plankton" has Plankton cut in half by a propeller.
- "The Splinter" is the shining example of this trope: SpongeBob gets an oversized splinter slowly wedged deep into his thumb. (In reality, something this deep in your thumb would be scraping the bone. Of course, sponges don’t have bones…) SpongeBob tries several painfully unsuccessful attempts to remove it which are cringeworthy because they're what real victims of splinters would go through if they couldn't get the splinter out. SpongeBob is tearing up from the pain, and he calls "Doctor" Patrick to help, but his so-called "help" consists of hammering the splinter further into his thumb so that it swells horrendously, and then the most disgusting part of the episode by miles, dumping garbage on the splinter wound so that it infects and bleeds pus. In the end, Mr. Krabs removes the splinter and it sprays pus all over his face.
- "Naughty Nautical Neighbors" has Squidward choke on a fork and fall over with his eyes open, complete with horrifying sounds.
- "Ugh" has Patar (the caveman version of Patrick) impale himself through his lips with a stick that he tried to eat.
- In "Pineapple Fever", Squidward is plucking his eyebrows and accidentally rips one off.
- In "Two Faces of Squidward", Spongebob hits Squidward's face with a door repeatedly, and you can hear Squidward's bones cracking as he groans in pain.
- In "SpongeBob Meets The Strangler", SpongeBob jumps on the titular Strangler's eyes while wearing cleats.Strangler: AAAUGH!!! Get your feet out of my eye sockets!
SpongeBob: I'm trying, but my cleats are stuck in your corneas! - The episode "Mall Girl Pearl" has the manager of Hot Dogs On A String cooked alive. Somewhat subverted when it turns out he's still alive, albeit badly burned.
- In "Sportz", Squidward Tentacles makes Patrick slice SpongeBob in half, and we can see his brain, ribcage, and intestines rather clearly. After this, their legs become very swollen, pulsating, and red.
- In "Code Yellow", SpongeBob performs a messy and gruesome surgery on Squidward. We see how SpongeBob accidentally makes Squidward bleed ink just by touching him, and them proceeds to take out his heart, only to accidentally dismember Squidward, to the point of decapitating him with a handsaw (although his head is later transplanted to another body after that).
