— Robot Krabs, "Imitation Krabs"

Robot Krabs is a robotic dummy of Mr. Krabs that first appears in the episode "Imitation Krabs." In all its appearances besides that episode, the robot is animatronic. He is mentioned in "Krab Borg."


Robot Krabs is a highly sophisticated robot that has many different features. Inside, from where Plankton controls him, there are hundreds of levers and pulleys to make the robot do many things. The robot is red and constructed from metal, with a metal suit as stated by SpongeBob. He has big eyes and his face acts and looks like a microphone. The robot appears to wear the same clothing as Mr. Krabs, but made from metal.

The robot has a self-destruct device activated by a penny inserted through a coin slot on his belt buckle. He can also disguise himself as a bread toaster.

One of the giveaways that the robot is not Mr. Krabs is that it periodically emits an exhaust fume with an audible noise from an exhaust pipe at the rear whenever it lies.

Role in series

"Imitation Krabs"

Plankton creates and controls the robot. It is accidentally destroyed at the end of the episode by SpongeBob when he puts a penny into the Self-Destruct Coin Slot, causing the robot and the Chum Bucket itself to be destroyed.

"Krab Borg"

SpongeBob and Squidward mistakenly believe the real Mr. Krabs to be a robot after seeing him exhibit all the features akin to robots in movies. They misleadingly cite him as "Robot Krabs" at one point.

"New Leaf"

It makes a cameo appearance in Mr. Krabs' closet, in which he keeps Plankton's old machines used in his attempts to steal the formula.

"Spy Buddies"

He appears to be rode in by Plankton. It may be possible that Plankton got Robot Krabs out of Mr. Krabs' closet.

"Goodbye, Krabby Patty?"

He's used in the Krusty Krab Museum to prevent Robot Plankton from stealing a fake Krabby Patty secret formula, showcasing that Mr. Krabs always stops Plankton form stealing the secret formula.

SpongeBob's Atlantis SquarePantis

Mentioned by Plankton in the console version during tank levels. Specifically when he says, "This is like maneuvering the Robot Krabs."

SpongeBob's Game Frenzy

In this game, there is a mini-game based off the episode "Imitation Krabs." Players have to avoid placing the coin in the Self-Destruct Coin Slot. If they succeed, Mr. Krabs himself bats the robot to the side and takes the coin. Failure causes the robot to charge toward the Chum Bucket, destroying it once again.


  • In one of the deleted scenes of The SpongeBob SquarePants Movie, "Mr. Krabs" transforms into this character. However, this was not included on the DVD/Blu-ray release.
