- Early Installment Weirdness:
- This is the debut of Plankton, and by extension, the Chum Bucket. However, there was only one room in the Chum Bucket that was shown in this episode only, and that room was the "lab". Justified, as that was just a joke.
- SpongeBob's trademark laugh also sounds...really off (lower pitched and more monotone) compared to later on. According to Tom Kenny, this was him still trying to figure out just how annoying he could make the laugh before it got unpleasant.
- This is also Karen's debut, but in this episode she merely serves the role of being a voice for the readouts of Plankton's analyzer, a far cry from the sapient computer cohort she becomes in later episodes.
- Establishing Character Moment: The entire episode is one for Plankton, but his first lines reveal his dream of getting a Krabby Patty and running Mr. Krabs out of business... and proclaiming that he went to college, showing his immense ego and obsession with having his accomplishments recognized.
- Excited Episode Title!: "Plankton!"
- False Friend: Plankton initially attempts to feign friendship with Spongebob in order to obtain a Krabby Patty from him, giving him a golden spatula with his name and an invitation to his birthday party. Spongebob quickly sees through Plankton's deceit though and leaves in a huff, prompting Plankton to resort to mind control.
- Flair Bartending: SpongeBob prepares a Krabby Patty by throwing the ingredients in the air, catching them with his pores, taking off his head and shaking it, and finally pulling it from under Squidward's nose.
- Food Porn: Spongebob's lengthy description of the Krabby Patty as he's about to drop it into the analyzer is so tantalizing that Plankton jumps out of his head just to get a bite of it himself.
- Grand Theft Me: Plankton takes control of SpongeBob to steal the Krabby Patty formula.
- Hammerspace: Plankton pulls a record player from Behind the Black and a full-scale spatula from behind his back. ("I've been keeping it in my secret compartment")
