On a freezing winter day in Bikini Bottom, SpongeBob and Squidward are at work, and Squidward notices Krabs has the thermostat set to 62°. Squidward, feeling cold, decides to raise it to 63°. Mr. Krabs bursts out of his office and complains about spending the money on heating and changes it back to 62° and then Squidward made rude comments. Plankton is spying on the restaurant and decides that night that he was going to change the thermostat and freeze the Krusty Krab. Mr. Krabs says that it is still on 62°; it was actually -15°. The customers started to leave because of this. When they came back, they were bundled in coats and then Plankton felt shocked. SpongeBob, meanwhile, was serving food on ice skates made from frozen patties. Soon, the customers began to strap patties to their feet and skated across the ice covered floor. Plankton goes in and attempts to steal a patty but gets pummeled by an ice machine. Then, as he tries to escape, some hockey players that were there to practice were blocking the exit. Plankton then remembers the thermostat and unfroze and froze the customers, but Krabs stops him and sets the thermostat at 100 degrees. The Krusty Krab is turned into a popular public pool the following summer. Mr. Krabs then thanks Plankton for his "good ideas."
This episode is one of the reasons why Mr. Krabs is a hated character on the show, according to a TV forum. This is because Mr. Krabs was selfish with the thermostat, not caring to change it under any circumstances even though there were ICICLES hanging from the roof of the restaurant. He apparently did not notice that the thermostat really was not 62 degrees and that the false temperature was written on a piece of paper taped to the thermostat.
When Squidward says "Thanks a lot" against SpongeBob because he gets into trouble with Mr. Krabs and SpongeBob happily replies, "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.
It seems that the thermostat also affects areas outside the Krusty Krab.
The numbers on the thermostat are digital, but Plankton wrote them in analog on his piece of paper. Mr. Krabs should've noticed this.
This is the 3rd time frozen things have been seen. The first was SB-129. The second was Suds.
This is the second time Plankton has hid inside something on Old Man Jenkins' tray. The first time was in "The Algae's Always Greener", where he hid inside his ketchup bottle.
The episode's title is French for "Krabs with Ice Cream". Also, the title is a pun on the food, pie a' la mode, which is French for pie with ice cream.
Clamboni is a parody of zamboni.
Plankton sarcastically refers to Karen as "the wind beneath my wings". This is a reference to the 1989 Bette Midler song of the same name.
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 SpongeBob gets unfrozen, all of his teeth are showing.
When one of the Krabby Patties lands on Squidward, it was green. In the next shot, it was brown.
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 doesn't give him the Krabby Patty, and just goes away with it.
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.
There are two Jimmy-Guses, one was scared from Plankton but he was in his winter clothes going to the Krusty Krab.
When Mr. Krabs turns the thermostat back to 62 o 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.
Plankton says "...I've found your Achilles' heel". This is an error because the sea creatures should not know about Achilles.
Moments before the scene with the frozen cash register the register is not frozen.
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.
