The Krusty Krab red alert mode is the mode that Eugene H. Krabs uses in the restaurant for profit or protection from Plankton. It first appears in "F.U.N."



It seals the Krusty Krab in thick metal sheets and turns off all lights except red alarms spread across. It seemed to be automatically activated on Mr. Krabs' notice.

"Pat No Pay"

The same build as in "F.U.N.," but with no darkening of the lights and no red alarms.

The SpongeBob Movie: Sponge Out of Water

The Krusty Krab gets covered in sheet metals. It seals off doorways and the order window. The metal sheets trap Squidward while at he was at his workstation.

"Plankton Paranoia"

The same as the original, but the Krusty Krab now goes underground. Also, it is activated by a button.



It is used to try to stop Plankton, but he uses a laser which makes a hole in the thick metal covering and gets away. SpongeBob ends up chasing him down.

Tales From Bikini Bottom

It is seen in the "F.U.N." segment of the book.

"Pat No Pay"

It is activated after Mr. Krabs discovers that Patrick won't pay for the many Krabby Patties he ate.

"Patty Caper"

Mr. Krabs activates this mode in response to the secret formula having gone "missing," so he orders SpongeBob to go outside and take the briefcase from the SWAT Team truck that contains it, intent on framing him.

"Truth or Square"

Mr. Krabs activates the red alert mode to have a discussion with SpongeBob, Patrick, and Squidward about Plankton's plans to steal the formula.

The SpongeBob Movie: Sponge Out of Water

When Plankton uses a robot to lure Mr. Krabs outside the Krusty Krab, he manages to sneak into the safe within a penny. Plankton sees the only thing that stands between him and the secret formula: a pressure plate. Plankton retrieves an identical bottle - a ship in a bottle - and uses it to push the secret formula off the pressure plate, and match the weight so as not to alert anyone. However, when SpongeBob walks in unannounced, he startles Plankton which causes the latter to tip the bottle off the pressure plate and the security system to activate.

A female computer voice announces "Initiating Lockdown Sequence" with a red alert sound blaring in the background. Metal bars come down over the windows in the office and metal doors slam shut between the office door and the kitchen. Metal sheets slide down rapidly over the exterior windows and the delivery window between Squidward's workstation and the kitchen. A metal cast of Squidward slams over him and traps him, as does a cast to a customer's beverage. The toilets seal shut, the Krusty Krab sign outside slams closed with a large padlock, and the exhaust funnel moves down into the Krusty Krab.

Mr. Krabs runs up just as the last thick metal is closing up the Krusty Krab and it slams shut before he can get inside. His panic, readily induced, causes him to have super strength and push the metal back open to go attack his nemesis.

"Plankton Paranoia"

It is activated after Mr. Krabs notices that the Krabby Patty secret formula isn't on the pillow, but it is later discovered that Patrick had mistaken it for a ketchup bottle.
