During the freezing, cold weather in Bikini Bottom, Squidward complains about the temperature in the Krusty Krab. When Squidward tries to turn up the heat on the thermostat, Mr. Krabs berates him, inferring that the thermostat is set so low because heating costs money, allowing Plankton to get an idea to freeze his competition out of business. He sneaks into the Krusty Krab late at night and takes toilet paper. He then starts rapidly changing the temperature on the thermostat, with an elderly fish coming out of the bathroom realizing he was locked in. The next morning, Plankton has frozen the Krusty Krab down to -15 degrees causing Squidward to complain even more than he already was, but Mr. Krabs does not allow him to turn up the thermostat because of the piece of toilet paper Plankton taped on showing exactly the same temperature as before. Squidward notes that there are even icicles on the ceiling and the customers start to leave due to SpongeBob and Squidward slipping everywhere with their food. Plankton sees the customers leaving and rejoices. He then puts up a sign saying that the Chum Bucket is warm and speaks to a fish walking by, who is frightened by Plankton's eye looking through the huge telescope. Plankton is angry when he realizes the customers come back in winter wear. Mr. Krabs has turned the restaurant into an ice rink complete with a train ride for children and SpongeBob invents Patty Skates to help him keep his balance, Squidward, and the customers to get around, which is bought by the customers telling SpongeBob not to cook them. Mr. Krabs is very happy that he is selling Krabby Patties without even needing to cook them and claims that he has made even more money than with the old Krusty Krab. Plankton sees Mr. Krabs with his money and is furious. Karen advises Plankton to swipe a Krabby Patty and he attempts to steal one but SpongeBob and the local hockey players (Who were actually trying to take the puck SpongeBob took by mistake) block the door after Plankton tries to run them over with the train but squashes them between the door. Plankton then goes over to the thermostat and reveals the true temperature, infuriating Mr. Krabs, and begins freezing and boiling the patrons by repeatedly turning the dial in both directions. He then falls off the dial, allowing Mr. Krabs to freeze him. Later, Mr. Krabs turns the Krusty Krab into a swimming pool, relaxing on a floating chair, while he thanks Plankton (trapped in an ice cube) for his ideas, and sips lemonade with Plankton as the ice in the drink, resulting in Plankton screaming.
This episode aired in Germany on May 31, 2007, before it aired in the USA.
The episode's title is French for "Krabs with Ice Cream."
When Squidward says "Thanks a lot..." against SpongeBob because he gets into trouble with Mr. Krabs and SpongeBob happily replied "You're welcome," it is similar to "New Student Starfish" where SpongeBob, who gets into trouble with Ms. Puff, does the same thing against Patrick.
After coming out of the bathroom, Old Man Jenkins says he is "Locked in again" which implies that he may have been locked in the Krusty Krab before.
When Mr. Krabs turns the thermostat back to 62° at the beginning of the episode, he turns it the wrong way, he turns the way it is to increase the temperature not the way to decrease the temperature.
Moments before the scene with the frozen cash register, it is not frozen.
When Nat is shown entering the Krusty Krab, he and the two other customers are smaller than SpongeBob, Squidward, Mr. Krabs and the two other customers.
When one of the Krabby Patties lands on Squidward, it was green. In the next shot, it was brown.
SpongeBob's Krusty Krab Employee Hat is missing when customers want patty skates, but it is back on when he delivers them.
When SpongeBob starts giving people patty skates he gives them uncooked burgers, not frozen patties.
The first time Plankton talks, the captions said: "[Male Voice]."
They also call Karen "[Female Voice]."
At one point, when Plankton is driving the Clamboni, Monroe Timmy and Susie Fishbowl do not have legs and Nat does not have lower legs.
When Plankton is freezing and unfreezing people, the water is waist high. But when he falls off, and Mr. Krabs freezes him, the water is only an inch high.
When Plankton falls in the water, Mr. Krabs freezes him using the thermostat. Mr. Krabs and every other person at the Krusty Krab should have frozen too since they were also in the water. It's possible that Mr. Krabs jumped while freezing Plankton on the ground.
When Mr. Krabs is relaxing in the pool, SpongeBob approaches him with a tray that has a Krabby Patty and lemonade on it. He says "Here's your Krabby Patty and lemonade." but while he gives Mr. Krabs the lemonade, he does not give him the Krabby Patty, and just goes away with it.
When Plankton was frozen, he should not be able to move if he is frozen.
