Trivia

General

• This episode, alongside "Squidiot Box," "PL-1413," "In the Mood to Feud," and "Kreepaway Kamp" serve as this season's 25th anniversary specials.
  • However, this episode and "Squidiot Box" seem to also serve as standalone episodes.
  • In its press listing, it is listed as a "sequel episode," likely to "Plankton's Army."
  • Coincidentally, this episode, "PL-1413," and "In the Mood to Feud" all star Plankton.

The full image.

• An image of this episode was accidentally released on the Nick.com website on February 13, 2024, being used as the thumbnail for the link to sister episode "Don't Make Me Laugh."
• This episode accidentally premiered on Nicktoons on February 21, 2024 at 2:27 PM EST.
  • This makes it the third time an episode premiered on Nicktoons before the main Nickelodeon channel, the other two being "Gary Takes a Bath" and "Buff for Puff."
  • Because it wasn't meant to air, YouTube TV removed the scheduled 3 hour recording of "The Curse of Bikini Bottom"/"Squidward in Clarinetland" that the episode aired during (this may have been due to the fact that the episode is only 30 minutes long but ordinarily they just fix the length of the recording).
• This is the first episode to be copyrighted in 2024.
• This is the first time Regigilled was shown in the main SpongeBob series.
  • Additionally, this makes it the tenth episode of the main SpongeBob SquarePants series to feature a character from a spin-off series. The first was "Something Narwhal This Way Comes," the second was "Upturn Girls," the third was "Slappy Daze," the fourth was "Welcome to Binary Bottom," the fifth was "You're Going to Pay...Phone," the sixth was "A Skin Wrinkle in Time," the seventh was "Abandon Twits," the eighth was "Salty Sponge," and the ninth was "Sandy, Help Us!"
• The plot of this episode is similar to the episodes "Plankton's Army," "Best Frenemies," and "The Other Patty," as all three episodes involve Plankton competing against another restaurant.
• This marks the first time we see Plankton's dad in the main series. Plankton's dad was previously seen in the book Hooray for Dads!, though he had a very different design.
• Cletus' gag "Did you say surprise?" routine and blowing something up is reminiscent of Sandy's "Did you say boom?" routine in "Mermaid Man & Barnacle Boy VI: The Motion Picture."

Episode references

• Several of Plankton's family members previously appeared in "Plankton's Army" when he was imagining what they looked like.

Cultural references

• This episode's title is a pun on the phrase "blood is thicker than water," a proverb in English meaning "that familial bonds are strongest."
