Who Killed Mr Krabs And How Did Mr Krabs Die

Now before you freak out and try to hunt down any sort of ‘who killed mr krabs episode’ on the internet. Let me reassure you that there is no such episode called ‘how did mr krabs die and who killed him’ nor any sort of official Nickelodeon animation of this nonsense.

This internet viral rumor is based on a mock-trial called The Trial of Spongebob Squarepants which was a school class assignment where the class was divided into teams of lawyers, and each team were assigned as either the prosecution (who want to prove SpongeBob is guilty) or the defense (who want to prove that he might be innocent).

I’ll explain more about the school class assignment and how you can do this for your own classroom a bit later, but for now let’s play along with this mock-trial and reveal what killed Mr Krabs.

What Killed Mr Krabs

Mr Krabs (from Spongebob Squarepants) was found dead inside of the Krusty Krab restaurant. His throat had been cut (do crabs have throats? lol).

How Did Mr Krabs Die?

The coroner concluded Mr Krabs was found with a serious cut to his neck and that the wound on Mr. Krabs’ throat was caused by a metal spatula found next to the body.

Who Killed Mr Krabs?

SpongeBob and Patrick are Prime Suspects

So who killed Mr Krabs? The four main suspects in the case were SpongeBob, Squidward Plankton and the fourth was Patrick!

The Mr Krabs Murder Scene Synopsis

The city of Bikini Bottom has been rocked with news of the death of Mr. Krabs, owner of the Krusty Krab restaurant. From the moment the under-water police discovered the gruesome scene, they suspected foul play.

At first, they thought the killer might be Sheldon Plankton, owner of the Chum Bucket restaurant and long-time rival of Mr. Krabs. But no physical evidence could be tied to Plankton.

The Evidence is pointed to Spongebob

As the investigation progressed, more and more of the evidence pointed to one of Mr. Krabs’ employees, none other than SpongeBob SquarePants himself.

SpongeBob insists that he’s innocent. The authorities don’t buy Mr. SquarePants’s claims, but he has found a team of defence lawyers who do. Some of the evidence does, in fact, seem to indicate that SpongeBob’s story might actually be true.

Whatever really happened, this is shaping up to be the trial of the underwater century!

You can make up your mind on who killed Mr Krabs by reading the full trial of Spongebob Squarepants. I do think Plankton was acting a little too fishy, but hey, that’s my opinion.

  • Plankton has a long history of trying to sabotage Mr. Krabs’ restaurant and steal his secret recipes
  • Inside SpongeBob’s home, investigators found a spatula with traces of Mr. Krabs’ blood on it. The spatula handle had SpongeBob’s fingerprints, as well as Mr. Krabs’
  • Three days after Mr. Krabs’ death, Plankton began selling a crab burger recipe on his website, www.chumbucket.ocean. The recipe was very similar to Mr. Krabs’ Krabby Patty recipe, but it wasn’t exactly the same.
  • During a search of Plankton’s home, investigators did NOT find the Krabby Patty recipe or any spatulas.
  • SpongeBob was the only person other than Mr. Krabs who had keys to the restaurant and knew the combination to the safe.
  • Two days after Mr. Krabs’ death, Plankton went to the bank and paid the remainder SpongeBob’s pineapple house loan. Plankton says he did this out of the goodness of his heart.
  • Sandy testified that SpongeBob was desperately in need of money because the bank was going to repossess his pineapple house. She said SpongeBob had recently asked Mr. Krabs for a raise. Mr. Krabs denied him, stating that the business wasn’t doing very well and there wasn’t enough money to give anyone a raise. SpongeBob was pretty upset.
  • Patrick said that SpongeBob told him, “Mr. Krabs is a greedy pig. He’s gonna wish he’d given me a raise!”
  • SpongeBob said that he went to the Krusty Krab restaurant the morning of Mr. Krabs’s death in order to beg one last time for a raise. When Mr. Krabs denied him again, SpongeBob told him that he quit. Then he left and went home to his pineapple. He said he believed that Mr. Krabs would have a difficult time replacing him and that he’d regret losing his best employee.
  • Squidward saw SpongeBob enter the Krusty Krab restaurant two hours before Mr. Krabs was found dead. An hour later, he heard Mr. Krabs screaming loudly. After waiting a while, Squidward went into the restaurant to investigate, and that’s when he found the dead body.

  • Patrick said he went to the Krusty Krab four hours before Mr. Krabs was found dead. The restaurant was locked, so Patrick knocked on the door. Mr. Krabs came out looking very upset. He told Patrick that the Krusty Krab was closed and that he might never sell another Krabby Patty again.

Pinterest - Who Killed Mr Krabs


  1. Really found the Mr Krabs Murder Scene Synopsis part gripping. It’s fascinating to see how elements from a light-hearted show like SpongeBob SquarePants can be woven into a mystery. It’s a unique mix that’s surprisingly engaging. I’d love to see more analysis on how the characters’ usual behavior is turned on its head under this scenario.

  2. Regarding the ‘Crime Scene Evidence’ section, were there any discrepancies in the presented evidence compared to the characters’ known behaviors? This could potentially indicate red herrings intended by the creators to mislead the audience.

  3. The Trial of SpongeBob SquarePants segment poses a rather intriguing question about morality and justice within the context of Bikini Bottom’s societal framework. It serves as a mirror to our own world’s judicial systems, and how public perception is shaped by narratives. Could SpongeBob, a figure of innocence, be a stand-in for individuals wrongfully accused due to circumstantial evidence? This opens up a broader discussion on the infallibility of justice systems in both the animated and real world.

  4. Loved the Random SpongeBob SquarePants Facts section! Discovering new trivia about SpongeBob never gets old. It’s always fun to learn more about my favorite undersea sponge and his friends. Keep these facts coming!

  5. The ‘Who Killed Mr Krabs Synopsis Video’ got me thinking. Are we overanalyzing a kids’ show, or is it really that deep? I mean, it’s a fun theory and all, but SpongeBob’s world operates on cartoon logic, right?

    1. Yeah, it’s definitely just for fun. The show itself is full of inconsistencies that are meant for laughs, not to be taken seriously.

  6. Jay’s approach to the ‘Who Killed Mr Krabs’ article was truly commendable. It took an element from a well-loved series and explored it with depth, engaging the reader with a blend of mystery and nostalgia.
