This episode connects with Friend or Foe, as it works in canon with that episode - Plankton could be referring to when they were friends when saying "Let's go back to the old days." It also connects to The Other Patty.
When Plankton waves a white flag and tells Mr. Krabs that he's given up the restaurant business, Mr. Krabs thinks there is writing on it and mentions that he is illiterate. However, in other episodes (and even in this one), such as What Ever Happened to SpongeBob?, he is able to read and write.
The items sold at the Chumporium include Lava lamps, Snow globes, Knickknacks, Teddy Bears and T-Shirts. Plankton also mentioned it could sell bubblegum.
This episode originally had The at the beginning of the title, making it The New Leaf. It was called "The New Leaf" during the Best Day Ever marathon. It is also called "The New Leaf" on the Nickelodeon schedule.
The rat may have died of food poisoning when eating the awful burger.
Mr. Krabs tells Squidward to dance or he was fired. Squidward danced with fear, as if he doesn't want to lose his job. This is odd, because Squidward hates working at the Krusty Krab. This may be a reference to Can You Spare a Dime? because he may not have wanted to lose his job again.
The scene where Mr. Krabs destroys the chumporium store is similar to the scene in the movie Falling Down when protagonist Bill Foster destroys a convenience store.
In Imitation Krabs, Robo-Krabs was destroyed in an explosion, but this time it's seen again in the pile of junk from previous episodes, without a scratch on it.
